I think people people finally figured out that they weren't safe economically working for companies after the pandemic. They were expendable during layoffs rather quickly. I believe now that they are starting their own side buisness, online sales etc..
The sad thing is that most of these companies are now offering higher wages than before and even handling out bonuses . So they could've paid higher wages before the pandemic but decided not to because they had the power.. now the power has shifted to the worker.
I don't feel bad for those buisnesses, they dug their own graves.
