“I did not go to college, but I made the right decision for me and my kids who were only 6 and 8. My Union provides me with pensions, a health insurance, and a rewarding career. I would never walk away from that.”

Jana Ashton
BAC Local 15 Missouri/Kansas/Nebraska

"The BAC gave me a life. I didn't have a life when I was working 80 hours a week, not being able to afford anything, not being able to go out, take a vacation, have a break, and certainly not able to retire."

John Myers
BAC Local 3 New York

“I have transitioned. My life is so much better. I have my own apartment. My kids are taken care of. Financially, I’m never looking back.”

Arkeem Watford-Mitchener
BAC Local 1 Washington/Alaska

"There is something in BAC to really help you advance your career. The union is an amazing thing. You have access to continuing education as well as traditional training that is all paid for. You don’t have to pay anything out of pocket. The wages are good, the benefits and the retirement are also great."

BAC Endorses Kamala Harris for President

As the Chair of the White House Task Force on Worker Organizing and Empowerment, Vice President Harris has played a critical role in ensuring that American workers and their unions have real influence on the direction of our government. It was her tie-breaking vote that ensured the passage of pension relief in the American Rescue Plan, the Inflation Reduction Act, and that confirmed Jennifer Abruzzo as the groundbreaking General Counsel of the National Labor Relations Board. She has put workers first on her agenda every day since becoming Vice President, and BAC knows that she will do the same as President.
