A note purportedly written by a disgruntled intern has been posted on online chat site Reddit, revealing that the young man had been spitting in his boss's coffee every day.
The unnamed intern was sent out to buy Post-it notes, and decided to slip a message inside - most of the way through the pad, in the hope that it wouldn't be discovered until after he'd finished his stint at the firm.
"By the time you read this, I'll be long gone from this s***hole," it read.
"I hope you enjoyed bossing me around. I bet you felt real good about yourself. Well, I wonder how you feel now knowing I spat in your coffee every day."
There's some doubt over whether the note is really genuine - another Reddit user points out that the poster does seem to have an awful lot of funny things happen at work, all of which get uploaded to the site.
And, generally, people do manage to wait until they're actually on their way out of the door before they tell the boss what they really think: like Goldman Sachs executive director Greg Smith, for example, who in 2012 quit via an op-ed article in the New York Times.
But disgruntled staff don't always manage to restrain themselves until they're safely out of the way. Some, indeed, get themselves fired before even starting the job.
Earlier this year, for example, one young woman who'd been given a job at a Texas pizza restaurant, posted her thoughts online. "Ew I start this f*** a** job tomorrow," she tweeted - only to get the reply from her prospective boss: "No, you don't!"
And survival expert Ray Mears recently lost a speaking gig that would have netted him £10,000. The organisers of the Caravan, Camping and Motorhome Show were less than impressed after seeing him on BBC show Room 101 - describing caravans as 'hideous' and 'ghastly'.
