(Bloomberg) — Grain workers at Canada’s biggest port went on strike Tuesday over a dispute regarding hours and pay, setting up what an industry association called a “devastating” situation for farmers during the harvest season.

With grain workers at Metro Vancouver terminals now on strike, Alberta farmers say this year has been stressful enough without this latest disruption that’s out of their control.
