vitamin model
a model proposing nine attributes of work that influence employee satisfaction. As with vitamins, employees will require some minimal amount or dosage of each attribute to be satisfied with their jobs. In the case of three attributes (money, physical security, and valued social position), employees can have an overabundance with no negative effects. However, too much of the remaining six attributes (externally generated goals, variety, clarity, control, skill use, and interpersonal contact) can lead to problems.
