Protesters are supporting a sacked electrician who claims he was let go by a subcontractor after raising concerns about the dismissal of a fellow spark.

The electrician claims his support for a former colleague at his tribunal led to him being transferred from the Media Centre to another site before being sacked following a disciplinary hearing.

The electrician claims his former colleague was dumped from the job because of his previous role as a union activist.

He said: “Late last year, a fellow electrician  was dismissed from site, this worker had an impeccable work record; 100% attendance and punctuality, he was earning a productivity bonus which meant he was achieving over and above his daily work target and he had an impeccable disciplinary record.

“I was in complete shock. The project was in mid flow and we were all looking at a minimum of at least six months work and the contractor we were working for seemed to have plenty of work in the pipeline for 2011.

“Later that same day, I was speaking to my supervisor and asked what was the reason behind the dismissal.

“The reply was astonishing, he stated he was dismissed because his name has come up on a list that he was a union man and a known troublemaker. The other electrician had previously been a shop steward on another London construction project.

“I passed on this information to the sacked electrician and his trade union. During the subsequent appeal hearing, the conversation I had previously recalled was divulged. That was the end of my Olympic experience.”

The electrician is now launching his own tribunal claim.

Members of the Blacklist Support Group will protest outside the Olympic site next Tuesday.
