About 270 workers at a Coca-Cola plant in Calgary are on strike as of Mar. 15.
Teamsters Local Union 987 says its members have been steadily losing job hours to third-party contractors.
The union says in a news release that workers have a reduced ability to earn a living for themselves and their families.
The affected workers voted 94 per cent in favour of strike action on March 4.
They work in warehouse, production, distribution and equipment service jobs.
The union warns the strike is likely to affect delivery of beverages to restaurants, grocery stores and other Alberta customers.
“These workers have dedicated themselves to keeping product moving to Albertans during a difficult time,” Teamsters business agent Brock Penner said in a release.
“Over the past year, these workers were deemed an essential service and have been there for Albertans. Now it’s time that Albertans stand with them as they fight for job security during uncertain times.”
