Overtime is based on working more than 40 hours in a single work week. If someone, for example, works 50 hours in 7 days, but those days are split or spread across two work weeks, he or she is not entitled to overtime. So if your hours are split across two pay periods--and thus presumptively two work weeks--then you cannot aggregate them for overtime purposes.Employers are not required to provide consistent schedules, unless there is an employment contract in effect requiring that.
