In reality people dont get fired here that easily....
unless you show up to work drunk/on drugs or verbally abuse a passenger (with a witness watching), the worst youll get is a warning...
Even if you open the door in the armed mode, they generally just send you back to training college....
at the end of the day when they spend thousands on flying you over here and training you up, moneywise its not in their best interest to fire you.
There are many employees here with 20+ sick days per year... (basically whenever they have a flight they dont want they call sick), also some with 4,5 absents per year.
Obviously they arent getting any upgrades with these kind of records, but they havent been fired either.
