In the last couple of weeks, I've been in contact with another company for a great position.
Although this other company offered me the position some days ago already, only today I've received the offer signed on their side.
I'm planning to sign since it is simply a great opportunity (without even considering the things that I don't like at my current company), and of course I need to resign at my current company.
The issue is that tomorrow afternoon my current company will announce a re-organization (nothing would change for my position, but I'm part of it). I would have resigned earlier, but only today I've received the signed offer. Therefore, I'm wondering if I should resign tomorrow morning or on Monday of next week.
On one hand, resigning before the re-organization announcement would be more "fair" to the company, but I also realize that it could backfire as I would give the company only few hours to deal with my resignation (definitely not enough) that could be seen as "yeah, thanks, too late".
Resigning on Monday would also be "too late", but maybe it would be a bit more "fair"?
My resignation will come as a surprise (although I pointed out quite some issues in the last 1-2 months), and I would like to leave the company with no hard feelings.
Note: I would start the new job in February 2022.
EDIT: company has ~250 employees. The re-organization is about one department "only" (around 50 people more or less). I am managing a small (growing in size) team.
