you will miss the trip, or you will get missed trip.. those are the only 2 choices you have..
what you are asking for is crazy..let me put your request the way management will hear it.
"Hi, i just started here and have some stuff i want to do in november that will require i be gone from work for 5 days straight during the holidays,, hope you guys understand.."
see how that isn't going to work.
in all seriousness though i don't work at mesaba, but you are probably on reserve and i don't think they have reserve lines that have 5 days off in a row.. i hope you get the time you want.
