What would you say was your most challenging payroll event?

Throughout COVID, our staff composition changed dramatically from almost completely permanent full-time staff to almost double the size and including a large portion of casual and temporary contract staff. We had to accommodate a multitude of ways to capture time worked (lots and lots of manual time sheets), calculating overtime and all the various scenarios that came with that due to the various unions, and master schedules. Our current payroll system just could not handle all the variations, so it was very manual and pretty painful. We had to create Excel databases to track the data so it was somewhat organized. Not efficient but less chaotic.

Testing and implementing a new payroll program while maintaining the same service level paying the employees in the old system until cutover.
