Strike action by Superstore employees in Alberta has been delayed.

The United Food and Commercial Workers union said 7,000 workers were considering an offer the company made last week.

Edmonton workers were to vote on the offer Monday and Calgary workers were to cast their ballots Tuesday.

The union wasn't making any recommendation on the offer. If it is rejected, pickets will go up at one minute after midnight Thursday.

Workers at Saskatchewan stores reached a tentative agreement with the company on Friday after 29 days of talks, while a strike was averted in Manitoba after the union's local in that province reached a tentative agreement on Sept. 2.
