Employees also hope to be promoted and feel that if they were a part of the union their opportunities would be restricted. Social pressure can also play a role in not joining the union. If the employee is working in a non-unionized environment, they may feel like they are a traitor if they joined a union. Employees who are pleased with their work environment and have no grievances against management may feel if they join a union then management may feel this is a hostile act by the employees. Even thought illegal in the US, employees fear if they join a union they may be fired due to union actions.
Cost is also a factor.
Members must pay an initiation fee and monthly dues. The monthly dues are usually one to two hours of pay per month. Employees may also have a religious or moral reason to not join the union. This is referred to as a conscientious objection. Some unions may also not accept a person who wants to join.
