Even though workplaces vary from organization to organization, when it comes to being clean it is a universal code for each employee. The mind and body have to be maintained at the best standards possible.
Personal hygiene is critical toward making and sustaining a good impression with customers and fellow workers. Take care of yourself and remember that colds and other viruses are normally passed at work and school. So if you are sick, stay away from the other workers. Your supervisor would rather you stay out than making everyone else sick by coming to the workplace spreading bad germs.
Your thoughts and words have to remain just as clean. Just like viruses, bad language and bad thoughts will inevitably make for a bad work place. From top to bottom, in and out, remain clean everyday in order to meet the demands of service.
