You can still get and transmit COVID if you are vaccinated. The vaccine merely reduces the effects of it so it is less potent to you. That aside I am not sure I really disagree with your assertion that many are just calling in sick. It is awfully suspicious that many people got COVID at the same time, but they are exposed to people from all over the world on a daily basis so maybe they are the "canary in the coal mine".
