This question already has an answer here:
I'm in my current company, in probation period, for 2 weeks now, and I have the feeling that I just cannot fit in with the culture and environment.
The colleagues here are kinda aggressive (in work-related issues). They are unprofessional compared to my last company (non sense and not on point emails, no sense of responsibility nor reliability...). More importantly, work is poorly organized. In the interview, my current manager did told me the job here is stressful, but I imagined it was stressful in a different way, not like this.
I kinda like my manager and I think he likes me. I know he had to do a lot during the recruitment process to get me the benefits I currently have. If I leave now, I'll put him in a really tough spot.
With that being said, it's still certain that I'm gonna leave.
Should I tell my manager the reasons, or should I say something comforting?
