Workers on overnight shifts could have their on-the job performance greatly enhanced by clocking in after midnight.

Researchers at Washington State University Spokane found employees who start work before midnight have to fight the body's circadian rhythm to get any pre-shift sleep in the early evening.

Scientists determined people whose shifts start between 9 a.m. and 2 p.m. are most likely to get a full eight hours of shut-eye.

Those who begin working between 8 p.m. and midnight tend to get the least amount of sleep and feel most exhausted on the job.
