FWIW, I think the comraderie is better at UPS, especially on the intl fleets. If money/stability is your deciding factor your choice is obvious. If QOL and enjoying your job is the key thing I would still say UPS. The pilot group here is superb and more than makes up for the uneducated manglers.
To understand out mgt you have to look at the background of the typical UPS non-pilot manager. They are almost always career UPS, meaning that they have had no mgt/leadership skills developed anywhere else. They are almost always a community college grad "working" on their 4 year degree and have a major chip on their shoulder when dealing with pilots who are more educated, smarter, wealthier, and better looking than they are.
