End of peak

Just curious as most hubs(not all) near end of peak are a lot folks just throwing in the towel?

I'm not just referring to the typical seasonal helpers who quit within a couple of weeks or a month.

For example, this past weekend one of our best seasonal loaders with great attendance for the past 2 months just called in to resign, no 2 weeks or anything. Similar is happening with multiple other great employees now that Christmas is basically here. Do people basically do this because they know getting picked to stay on is slim to none and they decide to cut their losses now?

Our coverage starting the season was great and now within the last week it's been pretty awful. I'm seasonal myself so it's more curiosity than anything. Our volume hasn't dwindled down yet but the line is basically bare bones this morning.
