Greg Heaslip wanted to take some time off work.
Heaslip’s line manager accidentally forwarded his holiday request to 3,500 staff members working at Arcadia, the retail group that owns fashion chains Topshop, BHS, and Dorothy Perkins.
And work for the day quickly ground to a halt as the #GiveGregTheHoliday hashtag was born.
The joke started off as an in-joke among Arcadia employees.
It apparently even broke someone's computer.
The joke soon spread across the internet.
Brands got involved.
Things escalated pretty quickly...
And then BOOM — TrekAmerica really stepped it up and offered him a free trip to Las Vegas!
And everyone pretty much lost their minds.
And brands kept on jumping on the bandwagon.
Arcadia later revealed Heaslip's holiday request had been OK'd before all the fun.
"The holiday request had actually already been approved on the system and Greg will get his holiday," a spokesperson said.
