Labor takes time, and that time is essentially purchased from an employee by an employer. That's kind of how jobs work. When a manager decides they don't want to pay for someone's time anymore, do they expect the labor to magically get done within a significantly reduced timeframe? It sure seems like that's what u/AssultTank1's general manager expected when she cut their hours so much that they weren't able to do their job properly within the new time limit. But instead of arguing, u/AssultTank1 simply asked their GM to put the demand in writing. It was a smart move, because when sh-t hit the fan, OP was more than prepared to expose the consequences of their boss' actions. Sweet, sweet malicious compliance.
“Oh yeah, I've been in management and I know if it isn't in writing, it didn't happen.” —OP
“Yep. Number one thing you can do before engaging in any malicious compliance is to get it in writing.” —OP
“I really did try to warn her with that, but hey... Manglement is going to mangle the situation.” —OP
“Cap up, lightly trimmed, internal temp of 190, salt and pepper only, 12 hour cook time, wrapped in butcher paper after 10 hours, hickory wood.” —OP
