I’ve just noticed that she is emailing everyone with the same generic message starting: Dear Tax Advisor, I need a chartered accountant. I have brought claims in Employment Tribunal against my employer for discrimination and whistleblowing detriment.
This is the first such repeated message I have seen for a long time. I have emailed her to ask her to stop and told her not to expect a response. Of course you are free to respond if you want to do so.
