tuff to do....but suck it up...continue to work as hard as you have been....and actively search for someone/something that meets your needs....hard workers are tuff to find....screw offs are a dime a dozen.
when you find it...offer the customary 2 weeks (most idiots will ask you to leave immediatly....no problem)....
if your good at what you do...which it appears you are....you will find the right home
I've been in the same position....upper management always wanting to raise the bar...change the game, always in their favor......they get one shot, after that, first opportunity....I'm gone, with my head high, and not looking back.....and NO second chance for them
