The important forces that make the employees join a union are as follows:
1. Greater Bargaining Power
The individual employee possesses very little bargaining power as compared to that of his employer. If he is not satisfied with the wage and other conditions of employment, he can leave the job. It is not practicable to continually resign from one job after another when he is dissatisfied. This imposes a great financial and emotional burden upon the worker. The better course for him is to join a union that can take concerted action against the employer. The threat or actuality of a strike by a union is a powerful tool that often causes the employer to accept the demands of the workers for better conditions of employment.
2. Minimize Discrimination
The decisions regarding pay, work, transfer, promotion, etc. are highly subjective in nature. The personal relationships existing between the supervisor and each of his subordinates may influence the management. Thus, there are chances of favoritisms and discriminations. A trade union can compel the management to formulate personnel policies that press for equality of treatment to the workers. All the labor decisions of the management are under close scrutiny of the labor union. This has the effect of minimizing favoritism and discrimination.
3. Sense of Security
The employees may join the unions because of their belief that it is an effective way to secure adequate protection from various types of hazards and income insecurity such as accident, injury, illness, unemployment, etc. The trade union secure retirement benefits of the workers and compel the management to invest in welfare services for the benefit of the workers.
4. Sense of Participation
The employees can participate in management of matters affecting their interests only if they join trade unions. They can influence the decisions that are taken as a result of collective bargaining between the union and the management.
5. Sense of Belongingness
Many employees join a union because their co-workers are the members of the union. At times, an employee joins a union under group pressure; if he does not, he often has a very difficult time at work. On the other hand, those who are members of a union feel that they gain respect in the eyes of their fellow workers. They can also discuss their problem with’ the trade union leaders.
6. Platform for self expression
The desire for self-expression is a fundamental human drive for most people. All of us wish to share our feelings, ideas and opinions with others. Similarly the workers also want the management to listen to them. A trade union provides such a forum where the feelings, ideas and opinions of the workers could be discussed. It can also transmit the feelings, ideas, opinions and complaints of the workers to the management. The collective voice of the workers is heard by the management and give due consideration while taking policy decisions by the management.
7. Betterment of relationships
Another reason for employees joining unions is that employees feel that unions can fulfill the important need for adequate machinery for proper maintenance of employer-employee relations. Unions help in betterment of industrial relations
among management and workers by solving the problems peacefully.
