2. Bring your pet with you
Virginia Commonwealth University conducted a study in 2012 that permitting employees to bring with them their pets at work will keep them motivated and decrease stress at work. It will also improve employee satisfaction and make them happy. The owners of the pets are not just the ones who benefit from this. All people who are coming into contact with the pets spend a few seconds to stroke it or hold it and they feel better. Less stress.
(Note: Policies on pets at work must be cleared up as well. Some employees may be allergic to cats or dogs and this must be taken into consideration.)
