I wish someone (anyone!) would have warned me about the leader at my current job before I accepted.

I wish someone (anyone!) would have warned me about the leader at my current job before I accepted.

If it's a truly bad situation, a brief but firm statement should be enough. simply state something along the lines of "for my own inner peace, I truly do not wish to *relive* or speak about my experience working at XYZ company."

Hopefully, your colleague(s) are perceptive and will understand your use of the word *relive* as a warning.

If pressed for more details, simply repeat the same sentence, and politely ask to not discuss that previous employer/company anymore.

That should gaive any conscious person cause to stop and think.
