Up to 1,500 former Thomas Cook workers are in line for awards of up to £4,200 after a tribunal found it failed to give the mandatory consultation notice before redundancies.
Staff at its London, Manchester and Peterborough offices lost their jobs almost immediately.
The tribunal awarded the maximum of 90 days’ pay for affected employees, said the TSSA.
TSSA General secretary Manuel Cortes said: “I’m delighted for our members and all those who were failed by both Thomas Cook and the government. Our union has fought for our members at Thomas Cook all the way and this judgment shows we have been justified.
“Our members endured harsh treatment from the start, not only through the actions of the company but at the hands of a government which failed to step in to save this cornerstone of our high streets when it made perfect sense to do so.”
The judgement does not include employees who worked at travel agency locations, who are subject to a separate tribunal.
