A union is an organization formed by workers who band together to have a voice in their workplace. Through their union, workers have the ability to negotiate from a position of strength with employers over wages, benefits, hours and working conditions. Unions help to ensure that employers act fairly.

By forming unions, employees can work collectively to improve working conditions and job safety, to resolve their grievances and to increase professionalism all around.Unions may also use their power to improve labor conditions, protect the middle class, shrink wealth gaps to balance the economy, assure equal access to public services and pursue other goals through legislative action.
