A mass meeting of Gatwick-based Thomas Cook workers who lost their jobs is being planned this week.

The Unite union is co-ordinating the session on Thursday morning, which will also be open to non-members.

Unite has more than 400 Thomas Cook employees who were based at the airport, which was the second largest of the company’s hubs behind Manchester.

Information will be provided on how to claim unpaid wages, securing redundancy pay and a legal claim called a protected award, for the failure of Thomas Cook to inform and consult its workers before making them redundant.

Providing assistance on pay issues is particularly urgent as the workers who were made redundant were due to be paid on Monday but have not been.

Instead they have become ordinary creditors of Thomas Cook and it is unclear when they will get paid and if they will only receive a percentage of what is owed to them, Unite warned.

The meeting will also provide advice on how Thomas Cook’s staff can seek new employment.

This will include advice on writing a CV and information on job vacancies with other airlines.

Unite has been working with other airlines since the collapse of Thomas Cook to fast track workers who lost their jobs into vacant positions.

An online petition has been started calling on business secretary Andrea Leadsom to intervene and ensure workers get paid what they are owed.

Unite regional officer Jamie Major said: “Thomas Cook staff are rightly angry about how they have been treated in being made redundant without warning.

“Unite will leave no stone unturned in ensuring that our members receive every penny they are entitled to.

“Unite is also providing assistance with linking Thomas Cook workers to vacancies at other airlines. This was an excellent high skilled and dedicated workforce, who possess a skills set that other airlines will welcome.”

The event has been organised for 9.30am on Thursday at ora Hotel, Southgate Ave, Crawley RH10 6LW.
