Helene Brown, BAC Member at Work

"My Union is my family."

BAC Local 21 Illinois member Helene Brown has been a proud tuck-pointer for over 17 years. She loves her job so much that she has introduced the building trades to all of her family members including her brother Gerald Brown, two sons Thomas Williams and Carl Williams and niece Jameelah Williams all of whom are PCC apprentices of BAC Local 21 IL. BAC Journal Editors (JE) recently had the pleasure of talking with Sister Brown (HB) about her Union experience and how BAC has impacted her life and her family.
