The Work Week Starts on defines the 7 day (168 hour) "Work Week" and the 24 hour "Work Day" used to calculate overtime hours.
TIP: If your overtime policy does not pay overtime based on hours worked in a work day, set the "or after x hours in a work day" to 24 hours. Therefore, employees will never go into overtime based on the number of hours worked in a single day.
TIP: If your policy does not pay doubletime, set the number of hours to the maximum hours in a work week (168 hours) or work day (24 hours).
NOTE: The employee's Work Week time should be based on the employee's normal shift. If the employee's shift crosses the defined Work Week, the hours worked in the work week start over at 0.
EXAMPLE: John's Work Week starts on Sunday at 7:00 AM. He works his normal 8-5 schedule Monday through Friday then works 6:00 AM - 2:00 PM on Sunday. He will earn 40 hours of regular time, and 1 hour of overtime (from 6:00 AM - 7:00 AM on Sunday). When he clocks out on Sunday, he will have worked a total of 7 hours in the new work week (from 7:00 AM - 2:00 PM).
