My employer in Kolkata makes me work 60 hours a week, what is the legal limit on weekly working hours?

The maximum weekly working hours are prescribed under the Factories Act, 1948, or the West Bengal Premises Tenancy Act 1997 applicable to shops and establishments in your state. For factory workers, no adult worker shall be required to work more than 48 hours per week and 9 hours per day, with weekly overtime not exceeding 50 hours. The Calcutta High Court has held that exceeding statutory hours without overtime payment is a violation of labour rights and attracts penalty. For shop and establishment workers in Kolkata, the state-specific Act may prescribe 8 or 9 hours per day with a weekly cap. Overtime must be paid at twice the ordinary rate of wages. The employer must maintain a register of working hours and overtime under the respective Act.
