Basically told my boss and HR I am quitting my job yesterday and they did not take it well at all. My boss was understanding but when it came to talking to HR they obviously tried to convince me (with more money and different job) to stay in the company, however I did not accept this as my mind is made up and I have several interviews lined up and almost hired in another company.
However, what pushed me to quit on the spot was their fearmongering techniques, it got really REALLY nasty and basically the person in charge of HR started implying that if I left now it would be bad, that I need to cover for my coworker that's going on a vacation soon (like thats any of my problem), it got to the point where they said they would not give good references of me and the “door is closed” if I ever want to go back and work with them. As soon as the call was over I was in shock, I calmed down and told them that tomorrow is my last day and I won't be working with them anymore. I handed in my resignation letter that same afternoon.
And I have to add, I am not a problematic employee and never was, never even missed a day of work. Yet I was treated like I was getting fired for doing something bad. Get fucked HR. I couldn't be happier with my decision.
