Mark Sebba has been the CEO of the fashion website Net-A-Porter for 11 years. And apparently his employees LOVE HIM, because he recently announced he's retiring, and THIS is what they did. (The company is pronounced Net-uh-pore-tay.)
Mark showed up to work in London last month to a HUGE going-away party, where employees danced around with signs to the Aloe Blacc song "The Man". Then a projector showed employees dancing at the company's other offices all over the world.
They posted a video of it on YouTube last week. It ends with him saying that he's overwhelmed. Then he jokingly orders everyone to get some actual WORK done.
