Workers exchange their labour for wages and working conditions. Individual workers have little power relative to their employer, and are only protected by minimal employment standards under the law. 

So workers combine into unions to expand their power and improve their rights. Under Canadian and provincial laws, unions have the right to represent their members through negotiations with the employer - also called “collective bargaining” because it is on behalf of the collective unionized workforce, not individuals. 

Successful bargaining depends on many factors, including member mobilization, economic conditions, political environment, competition and more. Understanding these factors is key to strategizing.
