Are you Jetsbest suggesting that your employer should put on extra services so that you don't have to layover so long or are you suggesting that your airline shouldn't go to that destination because you have to layover so long or are you saying that they should bring you home and fly someone else in to replace you?
I imagine he isn't suggesting any of those things, just that if you are away from home base for five days you should get paid more than if you are away for 48 hours. If you don't understand that you obviously have never had an office full of people you don't know deciding what part of the planet you'l be on and for how long every month. Sounds like a good system to me.
