1) Oft changing schedules with little notice;
2) Serious politics going on with a whole host of different "groups", the effects trickling down un-imaginably into your flight deck depending on who you are flying with on that day;
3) SIA management. If you don't like what you heard about SIA, you'll not want to be here;
4) Poor maintenance. All kinds of MELS, only 2 a/c opertaing while cannibalising from a 3rd aircraft;
5) No travel benefits. Your "Travel Allowance" would just about get you the lowest economy ticket that you found on priceline.com with the help of Capt Kirk;
Just a few, to whet your appetites
