Salary
Well, don't know what you expect in 2022 moneywise.. With 100 hours you get around 3.5k net, but don't expect 100 during winter months, 2.5-2.8 probably is closer to 40-50BH/m.
It is not VERY low for VIE, unless you want to rent 2 bedroom apartment in center for 1.3k.. Remember, with 5/4 roster you work much less than other guys. Plenty of commuting options to be combined as whole RYR network available in uniform for... FREE!
During winter can get part time roster, then only every second block of 5 days need to be on base, so 5/13 is the roster. 10 days even in hotel will be 500-700 depending on how spoiled you are. They offer options, stability and recurrency. Any other operator does it this year??
