What are the disadvantages of collective agreements?

Collective agreements can lead to inflexibility in wage and working conditions, as they often establish standardized terms that may not suit the diverse needs of all employees or industries. They may also create a power imbalance, where union leadership can prioritize the interests of a few over the broader workforce. Additionally, the negotiation process can be lengthy and contentious, potentially resulting in strikes or disruptions that affect productivity and employee morale.
