As we discussed in Stop Demotivating Employees Douglas McGregor explained theory X management (managers believe the workers will do only what they are forced, coerced into doing). Theory Y management starts with the premise that people want to do good work, the job of management is to help them do so (create systems, eliminate roadblocks, etc.). The whole post quoted above does a good job of explaining how to create that environment.
People ask me, “How can I get our employees to be passionate about the company?” Wrong question. Passion for our employer, manager, current job? Irrelevant. Passion for our profession and the kind of work we do? Crucial. If I own company FOO, I don’t need employees with a passion for FOO. I want those with a passion for the work they’re doing.
