Hi,
For more than 48 hours in a week and 9 hours in a day, one will be liable to be paid overtime. If it's 5 days of 8 hours each and the 6th day is 9 hours, one cannot argue that the 6th day is below 9 hours; therefore, overtime cannot be paid. In this case, the total hours for all 6 days amount to 49 hours, hence one hour of overtime needs to be paid.
Similarly, if it's 4 days of 8 hours each, the 5th day is 7 hours, and the 6th day is 9 hours, the total may only be 48 hours in a week. However, even in this scenario, one hour for the 6th day's overtime needs to be paid.
Therefore, the rule states that more than 9 hours a day and 48 hours in a week should be considered together to clearly understand the purpose of the law.
Regards.
