Encourage workers to practice good hygiene at work. Every restaurant has a sign to encourage workers to wash their hands after using the restroom. Washing hands at work is just as important for non-restaurant workers. Signs should be posted in lavatories that say to wash hands using hot water and soap for 20 to 30 seconds. There should also be antiseptic gel dispensers at the exit door of washrooms to give people the opportunity to disinfect their hands.

Employees should be encouraged to wipe down their personal surfaces such as computer keyboards and telephones. Ample supplies of disposable germicidal tissues should be part of the standard equipment to be found in office supplies and distributed to all employees. Disposable tissues should also be readily available.

Greeting protocols can be revised to let employees know that it's preferable to grasp the forearm of a colleague or client rather than their hand. Employees should be encouraged to cough into their shoulder or crook of the elbow instead of their hands. Employees should be encouraged to stay home when coughing or running a fever.

Cleaning personnel should be instructed to disinfect common areas such as refrigerator and microwave door handles. Foods in office refrigerators should be thrown out of weekly and refrigerators sprayed with a disinfecting spray to kill staph, mold and mildew.

Companies can have office air filters changed frequently and their ducts professionally cleaned annually.
Offices tend to have closed-air circulating systems and windows that don't open for security reasons. This closed environment is ripe for breeding and the spread of germs in the office.

Companies can organize and coordinate flu shots for employees. Conducting company blood drives not only helps the local supply of needed blood and plasma, but also signals to employees that the company takes health and well being seriously.
