$13 is simply not enough. The pay isn't enough to justify working longer than 6-8 months, getting a little experience and moving on to one of the other IT companies that pay $10,000-$15,000 more. $14/yr isn't the best incentive to stick around and make it to Helpdesk level 2.
There was initial talks during interviews of merit based pay raises and incentives and evaluations leading to pay increases but initial talks is as far as that got.
Understaffing = High call volume. Especially if you're on a newly launched project with strict service level agreements. They can sometimes lay the micromanaging on pretty thick.
Projects can change at any time. The desk you're at can get restructured depending on the clients needs. Your hours/job demands can change drastically, quickly.
