A British Telecom manager, fired over her part in a call generation scheme to disguise the fact that they were not answering sufficient calls, has been awarded more than £35,000 compensation by an employment tribunal.

Carol Clegg, 38, was dismissed after 22 years' service with BT after it was discovered she was aware of a practice involving calls being deliberately made to improve apparent performance on a contract for the Ministry of Defence. She was not the only manager to be disciplined but a Glasgow employment tribunal found her dismissal was unfair as no action was taken against other BT managers who were also aware of the practice.

But the tribunal found she was largely to blame by her own actions and cut her compensation in half to £35,153.

The tribunal heard BT would face additional costs if it failed to achieve the agreed level of service for the MoD call centre contract, which included emergency calls at call centres in Dumbarton, Kettering, Wakefield and St Helens.

An investigation was launched by BT security officers over allegations about calls being deliberately generated. It emerged that manager Chris Bean had instructed in 2002 that calls were to be generated to achieve service levels by any means necessary, including auto-dialling. Mrs Clegg, her manager and another manager had all been parties involved in the conference call. If anyone inquired about the calls, the answer to be given was that they were test calls.

Mrs Clegg said when she later became responsible for the contract, she issued instructions that call generation was no longer to take place.

But she was suspended in January, 2006, and dismissed in September of that year for gross misconduct. Mrs Clegg, of Campbell Avenue, Dumbarton, unsuccessfully appealed against her dismissal.

But the tribunal ruled her sacking was unfair. Tribunal judge Roderick MacKenzie added: "There is no doubt the claimant's conduct was culpable. The claimant could have been in no doubt that to generate calls was wrong, the effect being the respondents' customer may have required to pay more to the respondents."
