After reading some of the posts about people leaving crappy work situations I've decided to share my story.
I was almost three years into my career in the military when I sat down with my direct supervisor to discuss my future and I was interested in changing jobs. I was working as a computer tech for the Supply Squadron and I wanted to basically do the same job but on a grander scale for the whole base. The biggest reason for the change was the job I was in had a $0 reenlistment bonus whereas the new position had a $10,000 reenlistment bonus. He gave me the info I needed to make this happen and it was mainly getting good scores on my yearly reviews (for my first and second reviews I received fantastic scores) and doing good in the interview process.
I sat down for my yearly review with him about a month later and he docked me points in a couple of areas and his main reasoning was that he wanted to challenge me to be a better Airman if I was planning on making a career out of the Air Force. This review shut down any chance I had of changing jobs.
Six months later he pulls me aside to find out if I'm reenlisting and I tell him no. He wants to know why and he asked me to be completely honest. I told him that after all of my hard work and being in charge of the training for the four newest employees I felt unappreciated. I then told him “In the real world if you feel like you are getting disrespected by someone you work with you can tell them to FUCK OFF and not have to worry about being thrown in jail”. He asked me “Do you want to tell me to FUCK OFF?” and I said, “Absolutely not. I just like the idea that I can do that in the real world.”
The best part was after I left the military I called the office to check in with my former coworkers/friends and the person in charge of the office told me how sorry he was that they didn't appreciate my work and that they didn't know how much I was doing because everything was running so smoothly before I left.
It was a great experience overall, but it was nice to somewhat tell my boss to “FUCK OFF”.
TL;DR: I basically told my boss to Fuck Off before leaving the military and I was shown appreciation after the fact.
