I am a software developer that is leaving my current company in roughly 3 months. I'd like to do my exit as nice and professional as possible. At the moment the line manager and the project manager know about me leaving (for over 2 weeks now), but it wasn't yet announced to my colleagues (fellow devs) in the daily meeting.
So I'm wondering when would be the good time to tell my colleagues that I am leaving soon (given that I got another ~3 months to stay)? And should I tell them myself or leave it to the project manager?
