Timesheets are routed from the employee to the supervisor for approval on Sunday morning. They are auto approved to the payroll processor on Wednesday morning. Holiday weeks could shorten this time by one day.
The timesheets will auto- approve to the payroll processor who has no knowledge of the actual hours employees are working. The employee will be paid for the hours on the timesheet without anyone with direct knowledge of the work approving it.
You must pay the employee for hours worked, regardless of approval. If unapproved overtime is an issue you should remind the employee of the departmental guidelines for working overtime, and encourage flexing time to compensate (if appropriate). If this activity continues it becomes a performance issue.
When adding a note be sure you hit the add button on the right. If you fail to, the note will not be saved. Also, there is a scroll bar on the notes section, be sure you are scrolling through all the timesheet notes.
