Civil society organizations (CSOs) were developed to represent social values outside of the market and state sectors. There are two main types of CSOs - promotional groups that represent common attitudes open to all, and sectional groups that represent exclusive member interests. CSOs are stakeholders for businesses because they can raise awareness of problems, help set priorities, and inform future visions. While companies don't have to listen to every CSO, managers benefit from considering alternative perspectives. CSOs use tactics like research, protests, and boycotts to gain attention, though direct violent actions are difficult to condone.
