The programme allows Tui staff to spend up to 30 days each year working from “anywhere in the world”.
Tui said around 800 employees from across 34 countries had used the scheme, with average working stays abroad lasting 8.5 days.
Employees have so far worked in 82 different countries, according to Tui.
Germany-based staff were “particularly active” users of the Workwide programme, followed by colleagues from the UK and Spain – with Spain the most popular destination for remote working across Tui’s employees.
Italy, France and Greece were also popular locations for flexible working, along with Peru, Curacao and the Dominican Republic.
