I can't wait until you get laid-off/fired unjustly. I had this same attitude until I got laid off even though I was a high-performer (4/5 and 5/5 on all my bi-yearly reviews).

Now, I'm in it for me and only me. Fuck these companies, they don't care about you so why should I care? I perform to the expectations of my job description but forget going above and beyond.
