EDMONTON - Construction tradespeople defied a back-to-work order today in a growing revolt against Alberta's labour laws.
Hundreds of union workers shut down construction at Petro-Canada's billion-dollar refinery expansion, then staged a rally in front of the Alberta Labour Relations Board, near the legislature.
Major work disruptions were reported at some construction sites in Fort McMurray and at Shell's Scotford plant in Fort Saskatchewan.
'It's spreading,' Alberta Federation of Labour president Gil McGowan said of the job action.
