ABSTRACT:Unions have become an important factor in our industries. For many years, unions have been the primary voice of workers towards their employers. The ongoing effort of unions in helping workers secure their rights in the workplace, acquire all the benefits they need, and eliminate the injustice experienced by workers in the workplace is still an ongoing process. To understand unions in general, knowing their roots is the best way to start. This contribution will address the progress of trade unions throughout history, the problems faced, the developments achieved by them, the laws approved and the problem faced by trade unions today.
