Unless someone's putting a gun to your head & forcing you to take it, what's the big deal? As I have been told numerous times at my airline: Only bid for what you are prepared to accept. If you don't want it, don't put your hand up.
Don't get me wrong, I'm all for advancement in the workplace, but I recently turned my back on a command opportunity, because I wasn't prepared to commute or to uproot my family from our home & everything we enjoy about our lifestyle, just for the sake of a command. If I have to wait a few more years for an opportunity to present itself in my home base, so be it. It's taken me a long time to get this far, a few more years won't kill me. One thing's for sure though, I won't be lying on my deathbed wishing I'd spent more time in the cockpit.
