An employee was recently rehired using an existing empl record, and now we’re seeing that they are continuing to receive additional pay associated with their former job. What’s going on?

Recurring additional pay is associated with the employee’s empl record, not their position. 

There is an automatic process run by UCPath that ends additional pay once the empl record is inactive for 60 days. If an employee is rehired onto an empl record that previously had recurring additional pay within the 60-day window, the additional pay will persist on the new job. 

You should go in via the Create Additional Pay, or the PayPath Actions pages to end the additional pay.
