PARIS (REUTERS) - France's biggest union, the CGT, has called on electricity workers to strike on June 13 over fears jobs may be cut in the sector as a result of an ongoing review of energy policy.

"We have called for a strike on June 13 and we are now convincing workers on the ground," a senior CGT official told Reuters on the sidelines of an energy conference on Tuesday.

The official said the strike would likely result in production capacity cuts at nuclear plants.

The Socialist government is debating a so-called energy transition, with the aim of delivering a law in 2014, to boost energy efficiency and renewable energy, and lower the share of nuclear power in the electricity mix.
