Managers can BEST help their employees to maintain good personal hygiene by:

Modeling proper hygiene at all times is an effective strategy for managers to encourage good personal hygiene among employees. When managers demonstrate consistent personal hygiene practices, such as regular handwashing, maintaining clean uniforms, and following appropriate grooming standards, they set a clear example for their staff. This practice promotes a culture of hygiene within the establishment, reinforcing the importance of these behaviors.

Employees are more likely to adopt practices that they see regularly demonstrated by their superiors. By embodying these standards, managers help to establish hygiene as a priority within the team, allowing for a positive environment where employees feel encouraged to maintain their personal hygiene as well.

While the other options do touch on important aspects of hygiene, they do not convey the same level of influence as leading by example. For instance, although washing hands after using the restroom is crucial, it is a specific action rather than a broader approach to fostering a culture of hygiene. Letting employees know when to shower is not only subjective and could be considered intrusive, but it also does not actively engage employees in practicing good hygiene themselves. Wearing a hair net serves a particular purpose in preventing contamination, but it does not address overall personal hygiene practices in a comprehensive way.
