Beware the disgruntled employee, or so someone should have warned Marc Jacobs after an intern tasked with tweeting for the brand went on a rant over the weekend.

According to the Daily Mail, the @MarcJacobsIntl feed was updated via iPhone at midnight (EST) on Friday night with a series of aggressive posts aimed at CEO Robert Duffy.

“You guys and gals have no idea how difficult Robert is. I am only an intern. My last day is tomorrow. I wouldn’t be tweeting this if not!” the first one read.

Referring to the fact the company is using Twitter to search for a new intern, so followed: “Good luck! I pray for you all. If you get the job! I’m out of here. See ya! Son’t want to be ya! Roberts a tyrant! Seriously! He is tough!”

He continued: “I can call him out! I’m out! Won’t work in this town again! I know that! Learned a lot. But, I don’t have the energy for what is expected!”

And to finish: “Yea, walk in my MJ shoes! Don’t judge me! I’m alone in this office having to try and entertain you all. This isn’t easy. I have tried. Done!”

The posts were subsequently deleted, and a follow up post from the company added that read: “All is well here at MJ. Twitter is a crazy place. Protect your passwords.”

A lesson learned.
