Thomas Cook has reminded its staff of data protection processes after a document containing information about employees was found in the streets of Dundee city centre.

A passer-by handed the sheet of Thomas Cook-headed paper into the local newspaper. The paper reported that the document contained the names and payroll numbers of 20 staff in the Dundee city centre branch, as well as details of incentive payments they had earned.

It is thought seagulls ripped open the bin bags left out by staff, leaving the contents to spill out over the streets.

A spokesperson for Thomas Cook said this was a one-off incident and the document should have been shredded.

He said: “Every Thomas Cook store has a shredder to ensure the safe disposal of confidential information and we’ve reiterated our policy to our staff so that this exceptional case does not happen again.”
