Publication number: 20150012319Abstract: An employee location noticeboard is in the form of a dry-erase board, with a list of prepared options and checkboxes providing specific details about the employee's current location and estimated time of return. The noticeboard also provides some options that are not intended to be actually used, but instead may provide harmless amusement for the reader. A method of producing noticeboard content provides for determining legitimate reasons for an employee to be away from his or her desk, determining not legitimate but humorous reasons for the employee to be away, and printing the list on the noticeboard. The noticeboard features suction cups for easy mounting on an office door.Type: ApplicationFiled: July 6, 2014Publication date: January 8, 2015Inventor: Marja Lee Freeman
