I think servers have gotten the short end of the stick for a long time. Paying them well, and treating them right are first good steps.
I know when the pandemic started, in my small business, sales plummeted. I never laid anyone off, and hours were pretty normal. I had staff work on other projects that needed doing. Even gave out raises early. Didn’t lose a single employee. I’m not in the restaurant business, but treating your staff right is the first step.
