Hi All What are strategies that can be used if you find out (but not sure) if an employee is working two jobs at the same time? Is there anyway one can reach out to the HR? What other ideas do you guys suggest?

How is the performance of the person? And what kind of role/company/pay is the second job offering?

Performance has dipped and we suspect that the 2nd job is already taken by the emp and already working there as well
