Up to 15 workers at the Agnew gold mine in the Goldfields have been sacked and banned for life from every Barminco project in the world after performing the Harlem Shake dance craze on site.
The workers lost their six-figure salary jobs days ago for performing the stunt in the underground pit during a work break a week earlier.
A YouTube video showing the eight workers performing the convulsive dance has gone viral.
The Harlem Shake is the latest craze to sweep the world, with up to 4000 videos uploaded on the internet every day.
One of the sacked workers, who would not be named, accused Barminco of being too heavy-handed, claiming the tradesmen were only "having a bit of fun".
But a dismissal letter shows Barminco considered the stunt a safety issue and a breach of its "core values of safety, integrity and excellence".
The letter noted that Barminco would not allow the dancing workers "to be subcontracted by Barminco at any site domestically and globally" and said the electrical contractor did not have any other vacancies.
The unnamed worker said up to 15 people were sacked, including a handful who watched the stunt as it was performed but who did not participate.
Some were considering legal action to get their jobs back. One of the breaches included the failure of some workers to wear protective equipment, however the sacked worker said the shirts had been removed to ensure the Barminco name did not appear in the video.
Management had heard about the stunt from other workers and both Barminco and Hahn conducted their own investigations.A spokesman for Barminco said management could not be contacted late yesterday.
