Brian supervised 30 professionals in 5 city libraries. To cut the costs of unnecessary overtime, he issued this one-sentence memo to his staff:
‘When workloads increase to a level requiring hours in excess of an employee’s regular duty assignment, and when such work is estimated to require a full shift of eight 101 hours or more on two (21 or more consecutive days, even though unscheduled days intervene, an employee’s tour of duty shall be altered so as to include the hours when such work must be done, unless an adverse impact would result from such employee’s absence from hq previously scheduled assignment.”
After the 30 copies were sent out, Brian’s office received 26 phone calls asking for clarification.
