Participative management involves employees contributing ideas to solve problems and make management decisions affecting their organization and jobs. There are various degrees and techniques of participation, from simply providing information to manager-made decisions, to democratic group decision-making. Effective participation requires factors like sufficient time, participants having relevant knowledge, no power threats, and job freedom in the areas participants can influence. The advantages of participation include increased acceptance of decisions, responsibility and morale, better performance and coordination, while disadvantages can include increased time and costs if not implemented properly.
