Twice the ordinary rate of wages, under the OSH Code and the earlier Factories Act.
The OSH Code default is 125 hours in a quarter. Some states set different limits, such as 50 hours in Karnataka or 144 in Telangana.
After the normal working hours for the day (8 hours in the OSH Code baseline, more in some states) or after 48 hours in a week.
