What are the advantages and disadvantages of trade unions?

Trade unions offer several advantages, including the collective bargaining power they provide workers, which can lead to better wages, benefits, and working conditions. They also serve as a support system for employees, representing their interests in disputes with management. However, disadvantages may include potential strikes that can disrupt work and income, as well as the possibility of union dues and fees that could be seen as a financial burden for some workers. Additionally, unions can sometimes create an adversarial relationship between employees and management.
