Imagine you are head of human resources at Casual Contracting Co. Every month you hire a lot of temporary staff who spend 1-4 months with CCC before leaving. Sometimes you hire the same people again. Of late, you have noticed a strange process gap. You are paying same person two (or more) salaries.

More than 1,100 people attend the live webinar and hundreds more watched the replay. As part of the webinar, we had interactive Q&A.
