Case study: One garbled memo

To cut the costs of unnecessary overtime, she issued this one-sentence memo to her 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 (8) hours or more on two (2) 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 his previously scheduled assignment.
After the 36 copies were sent out, Joanne’s office received 26 phone calls asking what the memo meant. What the 10 people who didn’t call about the memo thought is uncertain. It took a week to clarify the new policy.
