Which of the following items is allowed to be worn by employees while working?

The option that allows for an employee to wear while working is the plain wedding ring. In many food service environments, guidelines for attire are put in place to ensure hygiene and safety. A plain wedding ring is generally considered acceptable because it is a simple band that does not have sharp edges or loose parts that could accidentally fall off or create hygiene concerns.

Other choices, such as long earrings and necklaces, may pose a risk of getting caught in equipment or coming into contact with food. Wristwatches can also be problematic in maintaining cleanliness, particularly if they have large faces or are not easily washable. Thus, the policy typically favors minimal and secure jewelry that can maintain a professional appearance while ensuring safety and hygiene standards are met.
