Which action poses a risk of working while ill?

Coming to work with a fever poses a significant risk of spreading illness to others, particularly in environments where food is prepared or served. When an individual has a fever, it often indicates an underlying infection or contagious illness, which can easily be transmitted to coworkers and customers. This can lead to outbreaks of foodborne illnesses, affecting not only the health of the employees but also the safety of the food being served.

In contrast, preparing food without gloves or handling food with clean hands involve different considerations about cleanliness and hygiene, but they do not inherently carry the same level of immediate risk related to being ill. Wearing hair nets is primarily a safety and cleanliness measure to prevent contaminants in food, rather than a health risk associated with the employee’s personal health.
