The challenges exist in all areas.
The labour shortage and aging workforce issue is not new. I think a witness gave the proof of that a little earlier, in fact. Recruiting is difficult, because working conditions and working hours are complex. For a flight attendant who has to work on a flight with a 6:00 a.m. departure time, for example, it is not easy to reconcile work and personal life when the day care doesn't open until 7:00. Not everyone wants to live like that.
