An Australian company that offered a job to "Anglo Saxon" candidates has apologised for the "completely unacceptable" blunder.
Optus, the country's second-largest telco, was looking for someone to fill a vacant retail role in one of its Sydney stores, so it put an advert on a job-hunting website.
It said its preference was for "Candidates who are Anglo Saxon and live near to Neutral Bay".
The response on social media was anything but neutral, and it wasn't long before the country's Race Discrimination Commissioner got involved.
"Under the Racial Discrimination Act, it is unlawful to discriminate on the grounds of race in employment," said Tim Soutphommasane.
"[We] will be investigating how this occurred with a view to taking disciplinary action against those involved," Optus spokesman Vaughan Paul said in a statement.
The ad was online for only eight hours. One Twitter user made fun of the phrase "Anglo Saxon", posting an image of medieval peasants building a "mobile phone tower" out of wood.
The Anglo Saxons ruled Great Britain from the fifth century until the Norman invasion in 1066.
