A sacred image
Many offices allow family photos on the desks. Why not a card with a sacred image? Another possibility is a small triptych, a type of icon composed of three collapsible panels, representing scenes of the life of Jesus and the history of the Redemption, aspects of Our Lady or of some saint of his devotion … It is more a beautiful way to help to sanctify your workplace and keep God at the center of everything you say and do!
