A Work Profile is a configuration which determines the Leave & Sickness allocation and Leave & Sickness settings for a user or groups of users. It defines the working and non-working hours for employees, whether their Leave is accrued or given annually and whether they are entitled to Carry Over and a Length of Service Entitlement.
For more information on Work Profiles including how to create a new one, take a look at the following article: Work Profiles.
If an employee's Leave or Sickness entitlement changes, you will need to assign them a new Work Profile.
Go to Organisation > Employees and select the employee.
From here, you can either click the pencil icon next to Work Profile, or click Options and select Change Work Profile. Either option will open a dialog.
Use the dropdown to select a new Work Profile for this employee and then click Save Changes. You may wish to visit the allowance calculator if you want to change the employee's allowance for this current Leave Year.
