Yesterday I gave my 2 weeks notice to my boss. I have been working for this company in a low management position since November 2015. My boss's reaction was so insulting, he just told me: “ok, we will work on a transition plan”. that's it!! no, I'm sorry you leave or thanks for the 6.5 years you gave to this company, NOTHING! I was one of the first employees of this company and I'm the most senior one. and just like this, 6 years of hard work and effort disappear.
I'm now happier than I've made this decision, and I will never put work in front of my mental health ever again.
