I've never seen this in any company I've worked at.

Personally, if I saw members on my team looking for work, I would want to understand that decision: is it for personal reasons, is it because they felt unable to grow, is it because of salary, or is it because they find the work no longer meaningful?

There are plenty of reasons to move on from a role. Firing someone for wanting something that aligns better with their future is beyond petty imo.

I hope you have considered sharing this with your team, especially, if any of them are at a point where job hunting & interviewing is ongoing.
