Sick Leave Based on Inception to Date Hours Worked

Hi - Our Sick Accrual Policy states  “new employees begin with a bank of 40 hours of sick leave credited to them when beginning their employment.  The bank is reimbursed with 3.69 hours per pay period until all banks hours have been earned".  (In reality though PT employees accrue at a different rate so this is equivalent to 0.0461 hours accrued for 1 hour worked).  Another way to look at it is that employees will be given 40 hours up front and after working 868 hours, all employees will begin to accrue at their appropriate 0.0461 rate/hour for the rest
