Nah, fuck that. Corporations regularly steal millions of dollars a year in wage theft from regular Canadians. We don't need to be punishing people who did the work from getting paid for the work they already fucking did. The more we normalize people not getting paid fairly regardless of why, we make it less likely for others to get paid properly and less likely for them to go to court over it.
