My guess is that both restaurants and hotels plunged a lot right at the beginning, and now they've recovered about 2/3 of that and that recovery has now stalled. People are still trying to figure out what is sustainable and what isn't, in terms of staffing.
We may not see this industry rebound to pre-covid employment levels ever. For instance, Uber delivery and other services may just be a thing and permanently shift labor away from waiters, and hotels may have permanently ceded market shares to AirBnBs or other lower service offerings. Maybe in the future, daily cleanings will be seen as some kind of odd luxury.
But I think it's all up in the air right now.
