See, there's a crucial difference in the two professions. A server is someone who brings your food, takes your check, and generally doesn't do much else. A nurse, on the other hand, needs to balance the life-saving care of dozens of patients at once while dealing with administrative bullcrap the whole time. People tip servers well to incentivize them to spend less time on their phones and dropping plates, and more time carrying food and recording orders accurately. You can't do that with nurses because they can't possibly give any more of their time. 91% of nurses experienced high levels of burnout in 2023,, and I'm dead certain that a lot of that is the insane workload. Twelve hour shifts working with uncaring staff and pissed-off patients must be soul-crushing. Then for your employer to try and disguise your looming pay cuts as "a way to give your healthcare heroes a special thank you" would probably cause an exodus from the profession; people can see through that stuff pretty easily.

You're still assuming this is going to be an immediate industry-wide thing, too. Like I said, people will see through the corporate bs, and they'll learn at some point that they can go to another hospital, not be expected to beg for tips from their suffering patients, and get paid more than the place that was lowballing them. Word of mouth is powerful. There's an entire cottage industry of Canadian nurses who cross the border into America for work because they're so dissatisfied with the Canadian system. Your scenario only works in a setting where there is only one nationwide hospital system that decides the market rate for nursing, and that people wouldn't decide not to become nurses after seeing that they're expected to tip them. We already see a nursing shortage because they're being treated so poorly; trying to make it a tipped industry would only make it worse.

As for the "would you?" thing, I can speak from a degree of personal experience here. I was in the psych ward in May and I was waiting for over ten hours in there to see a psychiatrist. I was tired, hungry, bored, and scared of what might happen to me. I was in no way equipped to make financial decisions at that point, and I get the feeling that the medical field would consider taking tips from someone who was in such an emotionally frail state to be unethical at best. (Oh yeah, and they took away my wallet. Couldn't give them cash if I wanted to.) My insurance made the cost of going there "reasonable," (mostly because I wasn't actually admitted,) but if the hospital expected me to tip the staff there, it would be nonsensical. How would you determine what the tip should be based on? The pre-insurance amount? That's like $5,000 there if I'm lucky, and 20% of that is $1,000 on a bill I only paid like $275 for. One word: No. The post-insurance amount? That's $27.50. A pittance compared to how much time and effort went into taking care of me, including the time it took to become a nurse to begin with. Furthermore, I would be so removed from the process of sending the tip that by the time the money reached the nurse(s) who helped me, they would only know me as a name on a bill at best. And again, would insurance be willing to cover the cost of a tip?
