How do you know when you're getting hosed?

So, the last several weeks at work have been just a tad stressful. I have been fighting a losing battle trying to deal with things. I have been trying really hard to learn to shut my mouth. This might work for some, but not so well for me! I have finally learned after 35 years to walk awAy, now if everyone else would just get on board! If I work circles around someone, then don't spend time trying to tear me down! Just let me work! Oh wAit... I forgot the rules of DOC!! Failure is expected, mediocrity is rewarded, and success will not be tolerated!! Anyone feel like you are working for no appreciation or recognition? Normally I am happy to just do my job, but sometimes It would be nice to get a thankyou!
