split
n.—Gloss: shortened form of “split shift.” «These restrictions create what is known as “splits.” Thus a bus operator may come to work at 4 a.m., work four hours until 8 a.m., then be sent home to report again at 3 p.m. and work four more hours to 7 p.m. So a bus operator is committing 15 hours of the day only to be paid for the 8 hours worked.» —“Unreasonable Schedules Bedevil Bus Drivers” by Mike McCoy TBO.com (Tampa, Florida) Feb. 22, 2008.
