What is inspectors duty time?
The regulations do not require rosters to be published for full-time members of the rank of inspector and chief inspector. Inspectors and chief inspectors are not entitled to overtime allowances or public holiday/rest day working allowances.

Where an inspector or chief inspector has been prevented from taking a day's leave on a public holiday, or from taking two rest days in any week, within the next twelve months, subject to exigencies of duty, s/he should be granted a day's leave in lieu of any public holiday or rest day not taken.
