58 of the Act makes it clear that a worker is entitled to allowance at the rate
of twice his ordinary rate of wages where he works in a factory for more than
nine hours in any day or more than forty-eight hours in any week. In other
words if the Management and the worker reach a settlement that an adult worker
shall work in a factory for 44½ hours in any week, even then his overtime
entitlement at the rate of twice his ordinary rate of wages will not be due
until he works for more than 48 hours in any week.
