Virgil Deemer and Thomas Cornwell, employees at a Whirlpool Corporation plant, refused to comply with a supervisor’s order that they perform maintenance work on certain mesh screens located some 20 feet above the plant floor. Twelve days before a fellow employee had fallen to his death from the screens. Because they refused to do the work assigned them, they were told to punch out and go home; reprimands were placed in their files. Should employees be able to pick and choose what work they will perform? Do Deemer and Cornwell have any recourse? [Whirlpool v Marshall, 445 US 1]
