For the second time in a month or so, one of the three people that does my job has made the same mistake. Our line manager is aware who has made the error on both occasions but has sent an email to all of us essentially bollocking us for it, copying in a couple of the company directors.
Every time there's an issue in the office, regardless who is at fault, an email goes to everyone saying why has this happened, make sure it doesn't happen again.
How should I word an email back to the manager (and possibly the directors that he copied too) asking why he doesn't deal with issues with specific people rather than sending a catch-all type round and pissing everyone off that hasn't done wrong?
