Due to COVID-19, as per the union's request, we agreed to work 7 hours (6 weekdays) including a 30-minute lunch break. The shortfall in working hours will be compensated once the situation returns to normal. Now that the lockdown is relaxed, the union is proposing to increase working hours to 9 hours per day (6 weekdays) including a 30-minute lunch break to compensate for the shortfall, making the total working hours 51 hours. This exceeds the maximum working hours permissible in a week of 48 hours as per the Factory Act. Will this proposed increase violate the Factory Act of 1948? Please advise.
