I work as a software dev and I'm about to change my job, signing new contract shortly. After I sign it I'll give a notice at my current workplace to my CEO. The management board is rather distanced from low-rank employees, so I guess if the CEO does talk about it to anyone, that'd be my project manager only, who may or may not relay that to the rest of the team (it's hard to tell).
There are quite a few reasons why I'm leaving, mainly because of a low salary, timeworn tech stack and overall terrible managing. In short: My colleagues are fine, the management is not (at least in their actions and decisions).
The notice period is 'till the end of the next month', so my coworkers will have plenty of time and opportunites to ask why I'm leaving. But how do I tell them my reasons without sounding rude?
While I don't shy away from socializing, being an introvert and a rather straight-forward person, I have a hard time formulating my thoughts in a way that would not be considered rude and I don't want to lie to anyone. I want to emphasize that my colleagues are great, they were always helpful and I really appreciate that. It's the management that's a problem here.
So, how do I reply when asked by the board, project manager or my colleagues for leave reasons without burning any bridges and without giving my colleagues an impression they could be at fault?
Edit about duplicate I'd like to emphasize on the fact that the question goes beyond just 'an exit interview' and it's not more about what to say, but how. I'm fine with giving a general answer to the board, my main worry is colleagues asking such questions. Giving them a general answer might not work that well, since we're on pretty good terms and have conversations on a daily basis and I don't want to sound rude or condescending etc while providing them with a satisfactory answer.
