The assistant is mouthy and throws his hat onto the ground as he is complaining. This led me to grant a warning to the coaches.

This is where you dump the ASSistant coach. Then, he would probably know by the next game not to screw with you or face the same outcome.

As he was talking with the manager I can hear one of the assistant coaches mouthing. He is complaining that we sucked on Friday and that we still sucked on Sunday. We cost them the game on Friday and we were probably going to cost them the current game. Then he states that I am a lazy official and was out of position and that if I hustled over to 1st I probably would have seen the player touch first. I had heard enough so I ejected this coach.

As soon as you heard the boldfaced type above, he should have been ejected (again, as he should have been run the previous game as well). Assistant coaches are to be seen and not heard, like small children.

As far as your UIC is concerned, you may want to check his wife's purse to see if his balls are in it. The better assignors will send you right back into the fire when a team threatens something like "we won't play if so-and-so is umpiring," or "you'll never work our games again," as if they have some kind of say-so in the matter. It always amazes me how much power coaches think they have over the umpires. Unfortunately, your "boss" is more concerned with not upsetting the status quo, which IMO is tragic. I always relished the opportunity to work the very next game with the mouthy coach who thought he called the shots, and my assignor was always more than happy to pencil me in.
