Simon Cowell's business has been caught advertising for "keen as mustard" unpaid interns to work in central London.
The advert, posted on a Facebook group entitled "OMG, we work in telly... but we're nice" was spotted by the careers website Graduate Fog, which shared it with BuzzFeed.
A spokesman for Sony, which runs Syco with Cowell, told BuzzFeed that the advert for unpaid workers at "You Generation" was "a mistake" that was removed after four days and they would not be hiring any interns as a result of it. The company said it also offers a paid internship programme.
One of the final comments on the "You Generation" job advert, posted shortly before it was removed, read: "If you are considering applying for this please make sure you understand the rules about unpaid work experience in the UK. This isn't some poor startup either - syco entertainment is owned by Simon Cowell. PAY YOUR WORKERS."
