I'm technical lead in a team of 40+ people working in IT. My current manager and his manager (the N+2 as we say) are currently on holidays (at least for another week).
One of our coworkers sent a very harsh mail today about leaving the company. In his mail he says he was insulted, pushed to quit and other very serious accusations. While not explicitly directed at my N+2, it's pretty obvious that he is one of the intended targets, especially as he put HR and the N+2's boss in copy of the email, as well as the N+2 itself and the rest of our team.
The guy was not well appreciated (or known) by most of the team, and I personally don't believe his accusations, not that it matters much. This mail will probably reflect way worse on the sender than anybody else but still, it will make people talk.
I happen to have the trust of/a very good relation with both my manager and the N+2 (I have their personal cell numbers for instance). Should I bother them during their holidays about how they should check this particular mail (and give them a chance to do some damage control) or should I just stay silent ?
