Yes, that is the case now.
I don't know the exact workforce retention rate, but I do know that we would have to hire a number of employees to get a sufficient pool of workers in a few months.
If we hire 30 people, it would be surprising if they were all still with us in six months. That's not the situation at the airports I know. We have to hire a lot of employees to make sure we retain some of them for the long term.
