A union is a group of workers who join together to advocate for their common interests on issues such as wages, working conditions, insurance, leave, pension, and job security.   Union members bargain collectively to create a stronger voice in negotiations with their employers. 

Unions are membership-driven, democratic organizations governed by laws that require financial transparency and integrity, fair elections, and fair representation of all workers.

Unions form across a wide range of occupations, including blue collar jobs such as electricians, white collar jobs such as teachers, and service worker jobs such as fast food.
