On the other hand, {playing Devil's advocate here}, the older guys maybe should get the better work/jobs as they have already "put in their time" with the crappy stuff.....kinda climbing the corporate ladder type deal. I don't think anyone should expect to be handed the caviar when they are the "newer guy".
If I were the "older" guy and the "good" work was handed to the "younger" guys, I would certainly raise holy hell!
Hopefully you are not moving back to the bottom of the ladder by moving shops.
