Agree 100%, for maintainers 12+ hour days are the norm. Don't even ask for time away to go to the gym, CBPO (ahem... MPF), Finance, BX, Class VI, your kid being born, etc... Had my ass handed to me once by my flight chief for letting a dorm guy go to the Post Office prior to a 30+ day TDY to pick up a package that had been there over a month. Couldn't go during "normal" hours; had report to work a good two hours before PO opened, went home well after it's closed. Thank God for the flightline chow hall, such as it was; if it wasn't for that, NONE of dorm rats would have hot meals Mon-Fri.
