In a groundbreaking moment for the retail chain, Indigo Books & Music workers at the Square One location in Mississauga, Ontario, have filed an application to join the United Food and Commercial Workers union. The vote to join UFCW Local 1006A will be held Sept. 21. The employees launched their campaign on social media (Twitter and Instagram) with video support from politicians such as Hamilton Centre MP Matthew Green, former MPs Olivia Chow and Libby Davies, and author/activist Judy Rebick. The news was also supported by bestselling authors such as Zoe Whittall and Naomi Klein.
