Union representatives in Alberta are calling for a boycott of Old Dutch potato chips after the company locked out its unionized workers at Calgary on Sunday.
The United Food and Commercial Workers (UFCW) Local 401 confirmed Wednesday that its members had been locked out at noon on March 29.
CBC reported Monday that about 170 workers, including warehouse and production staff and drivers, were picketing the facility.
"The lockout was really necessary to bring both bargaining units back to the table," Scott Kelleman, national director of marketing of Old Dutch told CBC.
Old Dutch has operated in Calgary since 1970, making Old Dutch chips as well as store brands for companies such as Wal-Mart, Safeway, Sobeys and Co-op stores.
