As a manager entering time off for an M&P employee on an intermittent leave of absence, can I enter an hour or two of sick time?
No. M&P time off, whether or not on a leave of absence, should only be recorded in half or full days. Any M&P who takes an hour of intermittent leave should work with their manager to make it up on a later date, just as they might do, for example, after leaving early or arriving late on any normal work day.
