Restaurant With Auto-grat Cuts Shifts Mid Service.

The restaurant I work at has 18% auto grat on all checks. Recently they started cutting servers mid service to save money. It’s a performance venue and we don’t close taps till shows end so when this happens we get nothing apart from minimum wage.

Is this violating some labor law? I go from 150$ in tips that’s guaranteed from the auto grat to nothing after doing 80% of the work.

You can’t withhold or keep servers tips but I’m not sure if since the sale hasn’t officially happed it’s not our money.

WA state.
