Graveyarder Syndrome 

The disorder in which a person who works a night shift and also has limited social contact (as a result thereof) feels the need to socialize as much as possible, as quickly as possible while a friend or acquaintance is still awake.

Mostly affects those who use social networking applications or text messaging during their work hours.

May also be experience by night owls.
