Giving You a Voice on the Job

Teamsters have the right to negotiate with their employer over wages, benefits and working conditions. Without a union, Management has total control.

Strength in Numbers

Teamsters organize and negotiate for improvements as a group instead of on their own, which evens the balance of power between boss and worker. Working together, bargaining from a dealing from a position of strength, we build power to make change in our workplaces.

Providing Protection & Support

Teamsters police workplaces to ensure our rights are being upheld, our contracts are enforced, and challenge unfair or questionable employer decisions.

Improving Industry Standards

Unionizing strengthens and improves health and safety, economic and other standards within industries and professions.
