Around 600 former Thomas Cook staff have attended special open days in popular holiday resorts organised by rival TUI.
In a statement, TUI said although the companies are competitors in the market, many employees of both companies were friends for many years.
"The news of Thomas Cook’s insolvency has also caused great consternation among the employees of TUI Group," it said.
TUI Destination Experiences, the division which handles TUI’s tours, activities and excursions, has held 25 open days in Spain, Portugal, Greece, Cyprus, Turkey and Bulgaria.
The last two events took place this week in Faro, Portugal, and Tenerife.
The events give Thomas Cook employees the chance to find out more about working for TUI and any job vacancies.
"Thomas Cook has many extremely experienced tourism experts who are of course of interest to us," says Annalisa Riches, HR director TUI Destination Experiences.
"We want to grow significantly over the next few years and are therefore looking for excellent specialists, whether in the area of travel reps, childcare experts, or also for digital and technology tasks and management positions.
"If, on the one hand, we could win Thomas Cook employees for us and, on the other hand, protect colleagues from losing their jobs, we could at least have drawn something positive from Thomas Cook’s regrettable insolvency."
