Night Duty & Overtime Allowance
Night duty definition, calculation framework and overtime triggers.
NDA Calculation Framework
One hour of night duty is weighted as equivalent to 10 minutes of extra daytime shift value. Hourly rates are derived from Basic Pay plus applicable Dearness Allowance (DA), divided by a standard scaling factor of 200, subject to prescribed 7th CPC upper ceiling limits.
OTA · Statutory Triggers
Overtime is triggered when duties exceed statutory rostered hours within the relevant classification cycle: Intensive workers — beyond 42 hours/week; Continuous workers — beyond 48 hours/week; Essentially Intermittent workers — beyond 60 hours/week.
OTA · Payment Rates
Calculated at double the ordinary hourly wage rate (2 × [Basic Pay + DA]) for every overtime hour beyond the statutory limits under the Hours of Employment Regulations (HOER).
