What tools and resources might be used in lieu of manuals to orient new employees?

Jason was excited about his first day of work at Jimmy’s Jungle Gym. As a second-year kinesiology student, this job would provide Jason with the opportunity to work with young children and teach them about active and healthy play.
Jimmy’s Jungle Gym was a play centre targeting 3- to 6-year-olds and provided numerous types of “play pits” and equipment for these youngsters to use. A café was also located on site, where parents could visit with each other, grab a snack, and wait for their children to burn off some energy. Located in a local strip mall, the Jungle Gym had opened 3 months ago and employed 1 manager and 12 general employees. During each shift, there would be 5 or 6 employees on site, with each person expected to welcome guests, collect cash, manage the café, and interact with the children in the play pits.
