canav8er is right, Monarch can not be compared to ryan air and sleezy. If the F/O's arent happy, leave! Monarch for some reason find it very easy to replace their crew.
Those ATC FO's work for basic only - until they receive there contract. They can always recruit them to scrape the bottom of a 321.
Monarch have a harsh whip and a memory like an Elephant. Complain to them and your Foubarred.
