Flying is one of the very few jobs where when you are away from it, you truly can be away from it. You can't get a build up of flights when you get back and as long as the company stays within it's own FTL scheme, then you can't get "extra" flights rostered in before leave.
Almost every other job in the industry is different. Go away and the work builds up and when you get back from 2 weeks away, then you just have a 2 week backlog to deal with.
My suggestion is that this is one of those whinges that in reality is like a toddler stamping their feet and shouting "it's just not fair" when they only got 2 bowls of ice cream.
It's neither becoming to public perception of aircrew, nor in reality is it reasonable.
Simply put, your company rostered you perfectly legally to fly. So go and fly. If they asked you to do something illegal or unsafe, then by all means do something, but in this case, you have no grounds for moaning whatsoever.
I mean, the cheek of them, expecting you to fly whilst they pay you? How very dare they...
