In her case, they cut her pay 25%, because it would be unfair to pay the other people less. This was right before COVID, and everyone basically quit - like a whole department of nurses en masse.
She came back as a contractor when they were hard up, at one point making $350/hr. All of the normal staff left and it became a contractor mill. When contract people didn’t show, she got $2000-3000 shift bonuses for a 4 hour work commitment to allow the ER to stay open.
I certainly hope the Slack folks do something similar.
