Total SA (TOT) said Friday around 900 contract workers at its U.K. Lindsey oil refinery are to have their contracts terminated after staging unofficial strike action this week.

"Total can confirm, with regret, that our contractors have now started the process of ending the current employment contracts for their workforce on the HDS-3 [hydro-desulfurization] construction project," the company said in a statement.

A spokeswoman at Total said the main contract company Jacobs Engineering Group Inc. (JEC) had informed workers of the decision Thursday. Workers will be able to re-apply for their jobs until 1600 GMT on June 22.

The 200,000 barrel a day refinery meanwhile continues to operate as normal, Total said.
