The flu and cold season is now approaching. Tragically, each year, a number of deaths result from flu and other infectious diseases. Employers again routinely face concerns about how to respond to highly infectious diseases when an employee reports such illness. Commonly known diseases such as the flu, chicken pox, and tuberculous, and newer threats, such as Zika virus, all have the potential to infect employees and shut down operations for weeks because of employee absence due to illness. Frequently, such illnesses are accompanied by co-employee stress as to whether they will also contract the disease because of workplace exposure. With a rising anti-vaccination movement in the United States, many employers have also learned that their millennial workforces are unvaccinated and susceptible to mumps,rubella, and other health threats.
