Employees who earn vacation may earn Conversion Rights. Employees who have accumulated a minimum of thirty days (240 hours) in their sick leave account may elect via the Sick Leave to Vacation Conversion Form to earn an additional 4 hours of accrued vacation in lieu of the 12 hours (prorated for part time employees) of accrued sick leave any calendar month there is no sick leave usage.
Per Iowa Code Chapter 63.3 (https://www.legis.iowa.gov/docs/iac/rule/11.63.3.pdf) and the university 4.57 Sick Leave policy (https://policies.uni.edu/457), any sick leave usage in a month makes an employee ineligible to make the conversion for the month in which the use occurs.
