At my employer, there are bonuses for certain nursing shifts, but everyone knows you're walking into
a dumpster fire. It's one thing to take those bonuses when you're walking into a good situation. I gladly took an extra $15/hr to stay 4 more hours because the situation was no big deal. How the nurses may be hearing the request is, "would you take $28 extra per hour to have an awful day? It will seriously burn you out and make you question your life choices."
