Place the mouse, trackball, or special keypads, next to the keyboard tray. Keep the wrist in a neutral position with the arm and hand close to the body. Adjust the height of the monitor such that the top of the screen is at eye level. Place reference documents on a document holder close to the screen and at the same distance from the eye. The way a task is performed and the workstation environment it is performed in can influence the risk of injury and general work productivity.
Good technique can make a job easy and safe.
Hold the phone with your hand, use the speaker phone, or a headset. Position the monitor directly in front of the user. Use the minimum force necessary to activate the hole punch and stapler. Take mini-breaks to rest the eyes and muscles. A break does not have to be a stop of work duties.
