Pretty much agree with Walla, I've done stints in Crewing down the years and I am always desperate to get back to ops where you are not relying so heavily on people.
Most Managers I have worked with seem to accept weather/tech a hell of a lot more than crewing failing to retreive a situation (normally an impossible one) so it tends to be a hiding to nothing sometimes, that said it is rewarding when it all comes together and not all crews will screw you over, but again I've seen many crew members blatently lie about crewing conversations and in any walk of life where you are in a 'my word against theirs' situation it is always going to be frustrating so a thick skin is a must.
Money wise where I am right now its a few grand lower than the Ops Contoller, but its more sociable hours (6-2 and 2-10) but I think you will only find that in the smaller operators although I am always surprised to hear how many mid size operators dont have crewing on the night shift.
Good luck with it, there are certainly jobs around at the mo with all the bods that have gone to Excel
