Traditionally the main way to conceptualise engagement was via money, promotion and other work incentives. Making the job stimulating was also seen to be important. But recent research indicates that what is truly motivating and engaging for employees is when their job links in some way with human relationships and a sense of mission. POS talks about engaging with, or amplifying an employee's 'calling'.
Professor Kim Cameron, from the University of Michigan, argues that the way to help employees see their job as a calling is to ensure that the organisation, and the employee's role, is related in some way to some wider, human concerns or to emphasis important virtues and values in the person's everyday role or in the organisation's core purpose.
