Employers, Employees And Labor Unions Under National Labor Relations Act (NLRA)

California Labor Law PostersAbout NLRA
NLRA stands for National Labor Relations Act. The law gives the employees the right to organize and form unions in order to bargain collectively for better terms and conditions at workplace. This law provides provisions for employees to ensure their own interests and welfare by engaging in certain welfare activities and putting their demands collectively before their employer.

A new or existing employee is free to join any union as per his choice and he cannot be forced to make a choice. He can even choose to stay without joining any union. Unions give employees a means to address their grievances and stand unitedly against any injustice or violation of interests.

The Law also accommodates features to ensure that none of the parties misuse the law and the vested powers by virtue of this law by providing the guidelines for each party. The elections of the labor unions and the grievance handling is done by a body called the National Labor Relations Board (NLRB).

The law is not applicable to the Federal, State and local government bodies and mostly applies to the private firms only. These laws do not cover railway employees, agricultural and individual employees and their close relatives.

Provisions and guidelines for the unions
As per the provisions of the NLRA, the workers can form a union for their collective interests. They can organize and collectively discuss among themselves for better wages, work hours and other welfare issues and later discuss and bargain them with the employers.

Employers in the from of unions can work collectively to enhance the working conditions of the workplace and improve it in terns of safety and convenience.

Every employee under the law has the right to join or form an union. They can also choose to assist any of the union without joining it. But it is not mandatory on the part of the employee to join an union. It depends completely on his will whether to join or avoid a union. He cannot be forced by some union members to join his union.

Same ways, unions cannot threaten an employee with loosing a job for not joining the union. This is illegal under the law for the union to force an employee. An union cannot discriminate an employee on the ground that he does not belong to his union and if such employee comes with a grievance, it is the duty of the union to address it. An union should also not try to influence the hiring process by making some undue and unjustified recommendations.

The law has been established that the employees address and bargain collectively in a good faith over genuine things. Undue demands and issues should not be promoted by the unions under the cover of the law. Hence, tough they can do strikes and picketing; they should ensure that the reason is worth doing it.

Guidelines for employers
The employer should be mindful and considerate about the rights and the welfare of the employees and should not try to discourage union and its activities. Hence an employer should not threaten, force or lure someone in form of bribes to discourage some union activity or to avoid joining some union. An employer cannot simply demote, fire or discriminate a person because he is indulging in some union activity. This is against the law. Similarly as an employer, you cannot hinder or stop any union activity that is happening at times other than work time. Spying and video graphing the union activities that are legitimate is also a violation to the act.

An employer should take the labor unions in good faith and heed their grievances and address them if they are justified. The employer is also protected by the same law for any inappropriate activity of the labor unions. Hence an employer need to have faith in the law and abide by his set of guidelines.

Complaint systems
Any act of discrimination or violation of the law should be brought to the notice of the federal agency NLRB within six months. The law stands for vested interests of the employees and gives enough protection to the employer against any unlawful or illegitimate demand of the union.

What is Content Marketing and Why is it Important?

Simply put, content marketing is all about how a business communicates effectively with existing and potential customers about their company, products or services in a meaningful and productive way. The prime tool in the stratedy is content. Content marketing is creating content that is valuable and relevant to targeted customers.

Content marketing builds trust in a company, creates a connection and increases brand awareness. Having trust and being connected to a brand makes a customer more loyal to the business. In this article we will discuss why content marketing is important.

It is an art of communicating with your customers
Content marketing is a great way to interact with your existing and new customers who find your brand interesting and buyable, with a goal of driving profitable customer action. To get your customers interested and engaged, content marketing is a way to attract your prospective customers, and establishes your business as a trusted source of information.

You are delivering information that makes your customer more intelligent
By providing valuable information to your potential customers, you are not only letting them know about your company, products/services, but you are also educating them on what type of products you offer, what are its features and how it is helpful. This information makes the buyer more knowledgeable and intelligent, which in return promotes brand loyalty.

Develops relationship and builds trust
People like to do business or buy products from brands whom they know and trust. When you engage in content marketing, your potential customers come to know about your business and trust you through your content.

Content marketing establishes you as an expert in your field. This leads to building trust and awareness. It is also a great way to develop a stronger and long lasting relationship with your customers.

Your customers want to share it with their social networks

Labor Laws for Women that Every Employer Should Know

Are you an employer having women employees in your organization? Then you must be aware of the labor laws that help in protecting women rights and equality in the workplace. The laws are created as a standard of fairness and equality. Some of the labor laws for women are listed below:

Women suffrage
Women suffrage is the right of the women to vote equally as men. Here, the women has power to vote the candidate who would protect the fair pay, labor rights and equality of women in the workplace.

Fair labor standards act (FLSA)
There are many issues covered under the FLSA, it also tried establishing equal wages and overtime pay for women. But amending this act, equal pay act came in to existence which aims at abolishing the wage inequality based on the sex. This laws or acts help women in getting fair wages as men.

Family and medical leave act (FMLA)
This act is for both men and women and is applicable for the companies who are having minimum of 50 plus employees. This act states that employer must grant an unpaid leave of maximum 12 weeks and also job protected leave to expecting employees for the adoption or birth of employees. This act not only gives job protection to women who decide to have a baby but also for the men who want to take leave or remain in home for taking care of his spouse, child or parents with serious illness.

Whistleblower protection
It generally includes many issues. But, when it comes to women, this protection is extend to the women who are victims of sex discrimination or reprisal by encouraging those with illegal knowledge and come forward by promising protection from unlawful judgment, percentage of money recovered, no risk of counterattack from a group accused or organization, protection from sexual discrimination.

Comprehensive omnibus budget reconciliation act (COBRA)
This act is beneficial for women, especially single mothers, who decide job transition or else suffer an involuntary loss of job, during the transition to new job, divorce, family death, hourly cut back which reduces from full to part time and other kinds of tragic life events.

Pregnancy discrimination act
This is an amendment to civil rights act of 1964 which exists to prohibit the sex discrimination based on the pregnancy, child birth, etc. This act states that women affected with pregnancy must be treated as other employees of the organization.

These are few labor laws related to women. So, every employer must know them and should implement the same in their organization for protecting women rights.

Surface mount technology in PCB

PCBs are an innovation. PCBs have made circuits sturdy, small and neat as compared to early boards. This is the through hole technology of PCB fabrication. With time and requirement, the size if the PCB started appearing bigger. As this is an era of miniaturization, further reduction in size of the PCB was required. To cater to miniaturization of the circuits, surface mount technology came into effect. The components lack leads and can be soldered on the same side of the board where the circuit is.

Features of the surface mount technology
As the name suggests, components are placed on the same surface where the circuit design is soldered. This saves the other surface of the PCB substrate and it can also be utilized to design a circuit and placement of circuit components. The circuit components for surface mount technology are different from conventional components. They are flat profiled, small and give minimum height and length to the circuit.

A metallic bed is prepared for them on the circuit. The components have metallic ends. The components are placed on the bed and are soldered on the same surface. Even though they are on the same surface, a few holes need to be drilled on the board to connecting the circuits through on the two surfaces. These are called vias. They are useful in expelling heat from a circuit.

Circuit components are designed specifically for surface mount boards, ICs, resistors, capacitors, etc. all come in a very miniature and small flat profiled form. The main and the basic motive is to minimize the circuit.

Advantages

  • The technology has become possible only because of the flat profile and small components. This has resulted in massive miniaturization of the circuits due to small component size, high density fabrication and utilization of both sides of the PCB substrate.
  • The data speeds are very good in surface mount technologies due to small track lengths and good circuit design.
  • The cost of production is low. Mass production of the components can be done and only few holes need to be drilled on the boards.
  • It offers less resistance to shocks and vibrations due to less height of the boards.
  • Low RF leakage and inductance at the soldering ends.

Disadvantages

  • Reliability of solder joints is a major concern. With the miniaturization, soldering area is becoming minimal. They can also be damaged by impulsive jerks and potting compounds while thermal treatment.
  • These boards are not compatible with breadboard sockets. Hence they are not friendly to test.
  • They are not suitable for high power applications.
  • Skilled operators and workforce is required to tackle the problems associated with surface mount boards.

How a Dry Sump System of Lubrication in Automobile Works

A dry sump is a lubricating oil management system which is commonly used in four stroke and big two stroke engines. It uses an external reservoir to store the oil and an external pump to circulate it. In four stroke engines, both lubrication and cooling is done by the lubricant oil.

Like the wet sump system, the lubricant still falls at the base of the crank case. But unlike the wet sump system, it falls to a much deeper collection area. From there it is taken to a reservoir which is outside the engine and is cooled and deaerated. The oil pumps that perform this are called the scavenge pumps and are also located outside the engine and they are run by a belt that is connected to the crankshaft. The pumps which draw the oil from the reservoir and send it back to the engine with pressure is called the pressure pump. Both of these pressure pumps are connected to and are run by the crankshaft. Due to their design, one pulley at the front can run a certain number of pumps according to the need of the engine.

Advantages of the dry sump system

  • The obvious advantage of a dry sump system is the increased oil capacity is offered by the reservoir which is kept away from the engine.
  • Since the reservoir is located in a different place and due to the thinner size of the sump, the engine can be mounted low in the vehicle. This provides better center of gravity.
  • Since the reservoir is external to the engine, it can also be used to improve weight distribution in the vehicle by relocating it to different positions.
  • Since more oil can be added due to the bigger size of the reservoir, it helps in better cooling of the engine and along with the transfer of oil, the blow-by gases also gets released.
  • Another important advantage is the issue of oil movement. In splash and pressure wet sump systems, due to cornering forces, the oil in the sump is displaced to a corner and the pickup tube would be uncovered temporarily. This problem is easily overcome in dry sump engines as the pickup pumps receive oil from the engine not by pressure but by gravity.
  • In a wet sump, excess of oil around the crank shaft can get on it and decrease horsepower. Studies show that there is increase in working efficiency as much as 15 hp by changing to a dry sump.
  • Easy to repair as it does not require opening up the engine.

Disadvantages

  • The cost is much higher compared to that of a wet sump, and is more complicated.
  • Since a separate tank is needed, extra space has to be managed for this purpose.
  • The pump requires its own drive belt, which makes it difficult to accommodate in front wheel drive vehicles.
  • The pump should be placed very low for good scavenging and this again takes up space which can be used by other components.

Electronics: A Friend to Medical Science

Apart from being a very indispensable industry, medical industry plays a very key role in every individual’s life for maintenance of the most wonderful machine, the human body. The industry stands as insurance at call for a wealth asset – your health.

How electronics benefits medical science
Since time immemorial, there has been several constraints inhibiting the reach of people to the medical care and industry’s access to technology. An understanding of the human body has been limited and that limits its diagnostics in case of an ailment.

The electronics industry came to rescue the medical science domain in overcoming these challenges and is providing them with the necessary tools and cutting edge technology. So, the human race is being served in a better way.

ElectroCardiography (ECG)
ElectroCardiography (ECG) is a method to record the electrical activity of the heart by placing non-invasive electrodes over the skin. Although invasive points can also be used to record the electrical activity of the heart. It’s mostly used for detecting and treating heart abnormalities and heart based research.

Before the ECG entered into the picture, transthoracic interpretation over the time was used.

The ECG apparatus keeps track of heart’s conductivity system. The polarization and depolarization of the heart because of the pumping generates electrical impulses. These impulses are used by the ECG to represent them pictorially in a graph. These graphical traces can later be used to know about various parameters of heart such as regularity of heartbeats, size and position, and the effect of drugs and pacemakers.

The ECG has achieved significant and historical modifications due to very advanced and innovative measures like critical alarm systems and data storage benefits.

EEG (EelctroEnchephaloGraphy)
EEG refers to recording the electrical activity of the brain through multiple electrodes that are places on the scalp. These electrodes vary the voltages that are caused due to change in ionic current in the neurons of the brain. These signals of small magnitude are amplified and represented pictorially in a graphical form. This technology is widely used for for analyzing and diagnosing sleep disorders, coma, epilepsy, tumors and strokes, etc.

Apart from these, they are widely used for monitoring brain activity, to determine the levels of anesthesia, and testing by World Anti-Doping Agency (WADA) test.

EEG is extensively used in the study of fields of neuroscience, cognitive science, psychophysiology, etc. for research purpose.

With the advent of CT and MRI technologies, EEG may lose its significance as it traces only the exterior signals and has a limited spatial resolution. Therefore, they can not give access to the drug target areas of the brain. However, they are still better than CT and MRI when millisecond temporal resolution is needed, which of CT and MRI systems cannot do – it’s their drawback.

Pacemakers – an artificial heart
Human heart is furnished with a natural pacemaker that regulates the heart beat rate. In cases, when the pacemaker is not performing up to its expected level and there is an irregularity in heartbeats as in case of arrhythmia, an artificial pacemaker has to be inserted to correct the heart beat pattern.

A pacemaker generally consist of electrodes that are attached to heart for detecting the beats and regulating them. In some cases, they consist of several electrodes to synchronize the lower chambers of the heart as well. Modern Pacemakers are programmable in nature, which allows the cardiologist to adjust to the requirement of the case.

The pacemaker is inserted under skin. Therefore, frequent pacemaker checkups have to be exercised by the patient.

Procedural risk and infection is a possible threat and demerit of this approach.

Computed tomography
X-Ray based computed tomography is gaining popularity over the traditional ultrasound and x-ray technology. This method produces the tomographic images of the sections scanned with the help of computer processed X-rays. A number of such virtual slices are stacked together to get a holistic and 3D view of the inside of the target part without cutting it open. This is very helpful in diagnosis of many diseases and abnormalities in heart, lungs, brain abdominal and pelvic region.

The CT scan comes as an advantage over traditional 2D approaches as it eliminates unwanted details and provides better resolution. The final images can be viewed in different planes to simplify the diagnostics.

The exposure of body parts to excessive and prolonged doses can result in the threats of cancer. Therefore, due care has to taken while carrying out these procedures.

Transition
The diagnosis and treatment by “machine” has achieved new heights with the help of electronics industry coming in rescue to the medical field and mankind. This is likely to help medical silence experts invent reliable and economically viable methods that could fight diseases and boost life expectancy.

The Working of a Car Suspension System

How comfortable does a passenger in a car feel if the car is traveling at an average speed, and the road has cracks and gutters? Not very much. On the other hand, imagine a car traveling on the smoothest surface possible at a high speed. Comfort will be maximum. The first scenario can happen as long the driver or passenger wishes to have it. But scenario 2 is a little different.

Horizontal and vertical accelerations
Apart from the comfort factor, if a surface is too smooth, there will be no traction for the wheels and so, even at normal speeds, the car would slip away from its path or sometimes the tires would even lose contact with the ground. Thus, some vertical force (one can call it obstruction) is needed for the car to grip onto the ground and move. Therefore, in order not to cancel out this vertical force and at the same time reduce it to a certain level so that the vehicle does not suffer too much damage, a system called suspension is used.

The suspension system
The suspension system supports the weight of the frame and helps it to maintain contact with the wheels always. The parts of suspension system are

Car chassis
The chassis is a very important aspect in a suspension system. All components of the suspension system are located in it, and ‘chassis’ basically includes a suspension system. It is prominent because it directly participates in the process of suspension. Apart from other systems, the chassis contains the frame and the suspension system.

The frame
This is the basic, framework that supports the entire weight of the vehicle and forms a platform to hold all the other crucial working components in place. Basically, it forms the skeleton of the chassis.

Coil springs
This is the most common of suspension devices. It is basically a hard metal bar wound around an axis and it expands or shrinks according to the vertical movements of the vehicle.

Leaf springs
This a set of metal bars combined together into a unit. The bars are also called ‘leaves’.

Torsion bars
The torsion bar is that which uses the twisting properties of steel as suspension. The ends of he torsion bar is connected perpendicularly to a wishbone. When the wheels receive vertical force, the wishbone presses against the torsion bar and receives torsion.

The shock absorber:
A vehicle’s suspension system cannot be successful only with springs. With just the springs, there is no limit or control about how much the vehicle will bounce when it hits a bump. This can result in a lot of undesirable things like acceleration squat, body roll and sway. The shock absorber is the most important device of a suspension system. It uses dampening mechanism to keep the springs in control and provide adequate support to the frame.

Technical Features and Advantages of a ‘V’ Engine

The V-type of engine has two rows of cylinders at an angle usually of 90 degrees. The working of a V engine is similar to that of a flat engine except the angle. Different angles of a v-type engine gives rise to different levels of smoothness. Some steep angles of the engine combines the advantages of V and flat engines and also the disadvantages.

Its advantages are its short length, the great rigidity of the block, its heavy crankshaft, and attractive low profile (for a car with a low hood).

Since it is short, it is compact and can be mounted easily. It is desirable in a vehicle with a small hood since the engine can be fit without negotiating passenger space. This engine lends itself to very high compression ratios without block distortion under load, resistance to torsional vibration. In-line engines have cylinders arranged, one after the other, in a straight line. Overall, V type engines are better and more powerful.

Usage
V engines are both used in cars and motorcycles. It is a highly preferred one in motorcycles due to its compactness.

Types

V2 (V-twin): Has two cylinders mounted in a ‘V’ shape. Most of The V-twin connecting rods share the same crank-pin. The cylinders can either be off-set in two different planes or can be set in the same plane using the ‘fork and knife’ connecting rods.

V4: V4 has been used in vehicles very less compared to the other V engines. The only advantage it has is that it is small in size and still can produce 140 horse power.

V6: The V6 has 6 cylinders, three of them joining the other three at a right angle or an acute angle. Like all V engines, all the pistons rotate the same crankshaft. It is a commonly used basic configuration of engines in modern cars after straight-4.

V8: A V8 can be defined as two sets of straight-4 cylinders acting on the same crankshaft. They produce more power compared to a V6, but has the disadvantages of being costly and consumptive on fuel.

V10: A V10 is two straight-five engines coupled together. V12 is slightly more complicated and runs more smoothly, while a V8 is less complex and more economical. V10 is not found much in common purpose in cars, but highly used in F1 racing.

The other V engines are V10, V12, V14, V16, V18, V20 and V24 as of today, where the number after ‘V’ indicates the number of cylinders.
