This just happened to bitwise industries. Employees had their checks and 401k stolen.
Wage theft is already a federal crime that the Department of Labor loves to investigate and retrieve up the 3x back pay for impacted employees. Caveat is that you have to report it to the feds. They don’t do random inspections; they investigate reports.

That, and it takes serious work to prove wage theft. You can’t just claim that they stole from you, you have to track your own hours, do the deductions that HR should have been doing for taxes and bonus pay for any overtime worked yourself, and then show your paychecks. Add onto that a degree of time where the wage theft is large enough to actually care about (nobody’s gonna bother doing this work over 20-100$) and it’s a lot more of a pain than one might initially expect.
