They may have. We don't know when or if things will go back to the way they were before March 2020 and how consumer and employer behavior will change.
For example, maybe movie theaters are completely screwed. Except as a novelty, the big business chains may not survive. Universal Studios is already pushing back on theater release windows and no live-action movies are being filmed right now, and who knows for how long that lasts. Will the public feel safe enough to go back into theaters all at once before theaters run out of money as if nothing happened? I imagine some of those jobs at least are permanently gone.
Employers will probably maintain work from home and cut back on office space. All those jobs that support maintaining offices may not come back either.
I don't think the restaurant business will jump back either, people can't just restart their failed restaurant as if they didn't lose all that money they needed to keep their already slim margin business open before the pandemic.
