I once took a job that HR said was one thing - technical writing, but the on-the-ground was a totally different thing - as close as I can describe was forensic accounting.
I went back to the HR folks and told then I was rescinding my acceptance of the job...
They seemed *confused*.
My reply was “Of I had accepted the job, I would say I quit.
Hence my recension of the acceptance. This owing to your dishonesty in the job description.”
Frustrating to say the least....as I had a bud from a former gig put in a good word for me.
I’ve worked in far worse places, so I can gut it our two more years.
