How to move OFF day to next working day if public holiday falls on OFF day?

Hi Experts,

We are using positive time management.As per reuirement, suppose 14th April and 15th April is OFF for a shift and 14th April is Public Holiday, then 16th April can be considered as OFF(but as per shift it is working days).

How can we proceed with this and if any employee comes on 16th April(as it is not OFF as per shift), the employee should be paid normal salary as well as working hours should be paid as per overtime rate hours. For eg: on 16th April, employee worked for 9 hours, then employee should get normal salary+9*1.5(Overtime salary rate).

Please advice on it and help me to provide your input soon.

Thanks and regards,

RG
