The VP of Administrative Services is in charge of the office Covid policy. We do have a Manager of Human Resources who is certified but for some reason is not involved in the decision making.
A staff accountant (call her Jane) who reports to me, sent me a text message on a Saturday to let me know she had tested positive for Covid. I forwarded it to my supervisor, the SVP of Finance. She let our VP of Admin know. Meanwhile Jane informed two co-workers who she had spent time with that she had tested positive.
