There are laws in place for service workers related to minimum wage. The employers have to make up the difference if tips don’t meet the rate for hours worked. It seems to me that’s not sufficient for the times.
Hypothetically, if everyone were to stop tipping in the U.S. would things be better or worse for workers? Would employers start paying workers more?
I worked with someone like that until she wanted to buy a house. Banks looked at her claimed income and gave a hearty “lol, no”. She started claiming all her tips after that. I don’t remember what happened after that (this was like 2003ish)
