Michael Muckenfuss worked in maintenance at a Tyson Fresh Meats facility. When the Covid-19 pandemic began, the town's mayor instituted an executive order mandating the wearing of masks, which Tyson enforced inside the workplace. Muckenfuss presented Tyson with a note from his health care provider requesting that he wear a cloth mask with a filter instead of a surgical mask as a reasonable accommodation for his asthma. Tyson agreed to the accommodation. Muckenfuss later sued, however, claiming that Tyson kept the mask mandate in place, along with his filtered mask, after the Covid executive order expired.
This statute was aimed to prohibit the introduction of a device "into" the body. Wearing a mask on one's face isn't that.… Mr. Muckenfuss invites an interpretation that would render this statute absurd.… [H]is interpretation would suddenly prohibit all sorts of sensible mandates by employers. No longer could a company require a bleeding employee from wearing a bandage or band-aid "against" his wound. No longer could a company require an employee to wear a protective glove, or work boots, or goggles, or many types of personal protective equipment because they were likewise designed to be used "against" the body.
