Transport Salaried Staff’s Association (TSSA) general secretary Manuel Cortes said the move would save hundreds of jobs, in addition to the more than 400 Cook staff Hays has already taken on since the iconic operator collapsed on 23 September.

Hays has pledged to reopen all 555 Cook stores "where possible".

“This is very welcome news offering real hope of re-employment to former Thomas Cook retail staff, many of whom are our members,” said Cortes.

“We have been clear from the start Thomas Cook was a strong brand and that it was likely parts of the business would be able to move forward as a going concern.

“Throughout the industry, the talent, commitment and skills of our members working for Thomas Cook was well known and I have no doubt they will bring the same dedication to Hays.”

Cortes added the union would now seek further details of the deal and an urgent meeting with Hays about the part it can play in Hays Travel’s “significant expansion” on the high street.
