Employees spend so much of their time in the office, which allows bacteria to thrive in the office environment. This is one of the most effective ways of limiting the spread of bacteria. Encourage your employees to get into the habit of properly washing their hands, especially before eating and after using the restroom. Place hand sanitizers or alcohol strategically to use in between washes. Proper office cleaning eliminates germs, bacteria, and allergens that cause asthma. Companies may also consider adding air filters throughout the workspaces to purify the air and air quality.
