Is there any problem in having my employees have small statues of the virgin marry and the like on their desk?
Although it isn’t very tasteful to have their statues where you walk past them and see then all the time. Halachically though, you wouldn’t have to say anything to them if they are only good luck charms, and they are not actually worshiping them. If they worship them, it should not be kept on your property.
