I think there's lots of gray area here. I don't have a problem going to work right now, depending on conditions. When I'm getting rerouted into multiple DHs, and then a NYC layover pops up, suddenly I don't feel so good about going to work.

My last trip I ended up in MIA for layover instead of RDU, and "enjoyed" multiple previously unscheduled DH legs. MIA isn't as bad as NYC, but none of these things were good for my personal overall stress level. I think if I had been rerouted in NYC I might have been a mess when I got home.
