Tui has announced plans to shut 166 high street stores, cutting its retail network to 350 outlets.
Around 900 roles will be impacted, with 70% of these employees set to be transferred to a new homeworking sales and service team.
Tui said it was not currently naming the stores that are proposed to close during the 45-day consultation period but confirmed that none of the shops that are currently open are at risk of closure.
The company added that it also aimed to relocate retail agents to vacancies across the remaining 350 high street stores, while UK jobs would be "protected" by closing third-party overseas customer service centres.
The company said the move to cut its retail network was being made due to “changes in customer behaviour” which have been accelerated by the Covid-19 pandemic.
