Make them fire you and file for unemployment, then challenge them when they try to get out of it.
I do not love the odds of a day laborer out maneuvering their professional claims denial behemoth in a court packed with pro-business Federalist Society flunkies.
Against some mom and pop porter service? Sure. But the odds of beating a company that vast and influential seems low.
Depends on the state. Some states are near impossible to get unemployment in. Others, it’s almost impossible for them to deny you unemployment outside of being violent or stealing from them. Know your state’s unemployment laws and use them to your benefit as best as you can.
My Mom managed to get unemployment in Texas against an oil company by spending about an hour total on the phone over a week.
Bonus was that the incident happened about a week before the Covid lockdown, so not only did she get unemployment, but also got the $600/week Covid unemployment bump.
