> How would you so them from emailing your employer?

My employer would show me the email, asked WTF and swiftly proceeded with legal action if applicable. My employer is there to make my life easier, and the fact that they do it in their best interest - the less time I spend on being stressed out, the more time and value I can contribute - makes me comfortable when asking for help.

But there may be a somewhat unusual level of trust between my employer and myself, maybe I'm just lucky to work at such a company.
