8. Attendance and late coming.--All workmen shall be at work at the time fixed and notified under Paragraph
4. Workmen attending late will be liable to the deductions provided for in the Payment of Wages Act, 1936.
In other words deductions for late coming can be affected only to the extent of late reporting for duties.
Even if the act is not applicable, deducting half day salary for 5 minutes of late coming is against application of cardinal principle of 'no work- no pay'; you can deduct only 5 minutes salary in such case.
