Trade unions are worker organizations bargaining collectively with employers. Functions: negotiate wages and conditions, protect members rights, provide welfare services, represent workers in disputes.
Methods: collective bargaining, strikes (witholding labor), work-to-rule (following rules exactly, slowing work), picketing. Union power depends on membership numbers and ability to disrupt production.
Nigeria Labour Congress (NLC) is the main union federation. Unions face challenges: unemployment weakens bargaining power, casualization of labor, anti-union employer tactics. Balance between worker rights and economic needs required.
