I joined my current company with a group of other people. We all came from a startup that had to close after a financing issue. It was a good deal all around: we didn't have to do interviews or search jobs or anything and the company gained a functional and cohesive group of 10+ very experienced workers to staff its R&D department.
The integration of our group has been... chaotic to say the least. We never felt quite at home and since we joined, project priorities got shuffled 10 times in a month, we lost 5 people already. Very recently my direct boss told me he was resigning too. I have been thinking whether I should stay or not, but fate decided for me when I was contacted last week by another company for a very interesting position.
From what I've seen from the previous departures, people leaving has been announced in very little groups and not widely to the 100+ person company. My boss is currently in his last week and only a few of us were told he would leave. Since nothing was announced publicly - I suspect to avoid a domino effect - he can't really say his goodbyes to everyone. As I am contemplating my own departure, I fear that I won't be able to do so either.
And it just doesn't sit well with me: I'm not leaving because I don't like the people there. I'm just leaving because I don't share the company's values. I wouldn't feel good leaving and not being able to tell all the people I know. I already plan to inform my closest coworkers anyway but that's as far as it can get. I don't want to make an announcement myself and act unprofessional or harm the company... but I don't feel good leaving and having people realize I'm not here anymore only when they try to reach out in the company chat.
How should I handle this?
