I worked at a job that fired me for calling the safe work authority in my Province (basically OSHA) which is illegal. I filed a complaint with them, they investigated again. I filed for unemployment, it was ruled in my favour. But the icing on the cake was me filing with employment standards and winning my case. They don't have to pay me a whole lot, but it's a nice chunk of money for the holiday season
Never lie down. If you're wronged, stand up for yourself. It may take 4 or more months like mine did, but imo it's worth the wait.
