Similar to a detention in the fact that you are kept behind after finishing
time,its a way for large multi national companies to hold employee's behind for working too quickly/
hard and finishing
early , usually involves some kind of team building excercise or pointless tidying up and painting .
Employee 1 "

time to watch the game tonight"
Employee 2 " I doubt it! the boss has just given us an After
work detention "
