At Whirlpool’s manufacturing plant in Ohio, overhead conveyors transported household appliance components throughout the plant. A wire mesh screen was positioned below the conveyors to catch falling components and debris. Maintenance employees frequently had to stand on the screens to clean them. Whirlpool began installing heavier wire because several employees had fallen partly through the old screens, and one had fallen completely through to the plant floor. At this time, the company warned workers to walk only on the frames beneath the wire but not on the wire itself. Before the heavier wire had been completely installed, a worker fell to his death through the old screen. A short time after this incident, Deemer and Cornwell, two plant employees, met with the plant safety director to discuss the mesh, to voice their concerns, and to obtain the name, address, and telephone number of the local Occupational Safety and Health Administration (OSHA) representative. The next day, the two employees refused to clean a portion of the old screen. They were then ordered to punch out for the remainder of the shift without pay and also received written reprimands, which were placed in their employment files. Does Whirlpool’s actions against Deemer and Cornwell constitute discrimination in violation of the Occupational Safety and Health Act? Explain.
