As a worker, you have a right to form or join a union, and bargain collectively with your employer. Stewards are the representatives of the union who help workers deal with unfair treatment, discrimination, and other workplace issues. This helps balance the power that an employer has over individual employees.
Belonging to a union gives you rights under the law that you do not have as an individual. Once you have joined a union, your employer must bargain with your union over your wages, benefits, hours, and working conditions.
Union workers, on average, earn higher wages and get more benefits than workers who don’t have a voice on the job with a union.
