Final answer:
Employees must follow the CDC guidelines for hand hygiene.
Step-by-step explanation:
The guidelines for hand hygiene that employees must follow are from the CDC (Centers for Disease Control and Prevention).
The CDC recommends five steps for typical handwashing for the general public, and surgical scrubbing is more extensive, requiring scrubbing from the fingertips, extending to the hands and forearms, and then up beyond the elbows.
These guidelines are important for preventing the spread of germs and maintaining good hand hygiene in healthcare settings.
