I like the way you phrase the Q because it suggests you sense the answer. Yes, you do need to disclose BUT without disclosing the employee’s identity–at least without his/her express consent. That’s because the employee’s identity is protect information under personal privacy laws. And, as we discussed in a recent story about privacy and flu risks, there’s a consensus among the major Privacy Commissioners that disclosing the name of an employee suffering from a contagious and infectious illness is NOT permitted without consent.
Thanks for asking. Hope that helps. Glenn
