The luxury operator, which employs 160 people across its Inspiring Travel Company, Regent Holidays, Rainbow Tours and Spectate brands, will be giving all staff a day off to spend time with friends and family within the latest guidelines.
From 29 March, outdoor gatherings (including in private gardens) of either six people or two households will be allowed.
A year on from the start of lockdown and "following what has been a challenging time for the nation", ITC said it was "delighted to give its hardworking team the time to make the most of this long-anticipated day".
The luxury operator said its 160-strong team will be encouraged "to grab their deck chairs and picnic baskets", get outside and reconnect with their loved ones in parks and gardens locally.
"This is the first time in our 47-year history that we have closed our business during working hours," said group chief executive Phil Aird-Mash.
"Our team have worked incredibly hard over the past year, and we’re pleased that we can show our gratitude and allow them to enjoy the things that mean most – family and friends – as the country begins to open back up on Monday."
ITC Travel Group recently launched a digital toolkit for agents, providing an online portal with assets to support marketing.
