Unifor has filed an unfair labour practice complaint against Amazon amid a vote by workers at a Delta, B.C., warehouse over whether they want to join the union.

The union claims Amazon beefed up its workforce as Unifor was in the midst of a union drive to try and weaken support.

Amazon denies the allegations and has said it plans to appeal the labour board鈥檚 decision to call a vote.

The vote by the warehouse workers closes at noon B.C. time, but Unifor鈥檚 Western regional director Gavin McGarrigle says the results may be delayed until the challenges regarding voter composition and the unfair labour practice complaint are ironed out.

He says that Unifor is not intimidated by Amazon, and that the union will stand with workers 鈥渆very step of the way.鈥�

Earlier this month, workers at an Amazon warehouse in Quebec voted to unionize.
