I understand about the workweek and the 7th consecutive day, but is there a required amount of hours that must be worked in the previous 6 for this rule to apply. In other words; If an employee works 1 hour mon, tues, wed, thur, fri and sat and has a total of 6 hours, are the first 8 on sunday still time and half

Thank you

Correct. The number of hours worked does not matter.
