While you're complaining about others complaining, which I have to admit is a nice touch, there are some folks over there at Republic that are working to make things better for everybody there, including yourself.
Now I don't mean to come down too hard on you, but instead to enlighten you to the plight of your soon to be coworkers. Republic has got some good folks from the ones I know, and none of them are the type to complain for no reason. Everybody I know over there is a hard working, honest to goodness good person, and instead of wondering why they could complain so much about their gig, how about you try to realize that they were once like you, and are in the position they're in for a reason.
Once you understand that reason, you'll understand why folks are so upset.
