Each employee receives $30 from the company to spend on drinks or food. To do this, employees must meet in groups of three from 3 p.m.

If they have not been asked to notify superiors in advance, they must nevertheless publish a photo, capturing their moment of conviviality, on the professional messaging application Slack. The program even has some success with employees since photos are posted four to five times a day on the “3- 3-3” Slack channel.
