I would say that today's managers would most likely use the tool of teamwork in their employee relations as that is the model in university and colleges now to do projects in a team and acknowledging that no one person has a monopoly on all the knowledge required to complete a project the wise manager will pool the resources and become mainly a co-ordinator and facilitator for the current team for a particular project. Many different skills, trades and professions can be on a team ie electrician, geologist, pipefitter etc.
