I work in the Programming industry. I hired a guy to work with me. He was older although had a great resume and I couldn't understand why he was unemployed for so long. He explained later that he thought it was ageism. I didn't care; I just thought he would help me step up my department's output. Well, 2 years later, the department output has greatly increased... and he's been making my life hell. Simply put, he wants my job.
He complains to higher-up's that he's more qualified and outputs projects faster. The quality of our projects is equal, although he does output projects faster than me. Not a lot faster, although faster. I make more money as I've been there many years longer. He's received yearly merit raises, although he told me that knowing that I make more money than him really makes him angry. He's actually on the same path as myself regarding salary.
The work environment has slowly become toxic. I've been trying to stay positive and stay focused although his anger and need to always push past me has me worried. I've noticed I'm becoming less confident and have been losing sleep over this. I started to look for other positions although nothing comes close to my current salary. I have a family and seriously can't afford to jump ship.
The higher-up's have noticed that his output is faster and have joked with me in meetings that it looks like I need to step up my game. I laugh it off although I feel like I'm sinking. I meet all of my deadlines although I've noticed that I've been putting in longer hours to get things in faster. I feel the constant weight of stress that I can't seem to shake. I used to enjoy my job now I find myself always looking in the rear view mirror.
