What is the difference between personal power and position power?

Position power comes from top management, personal power comes from followers based on the leader's behavior. When we talk about position power it comes through a chain of command. Managers can have both position and personal power, but non-managers can only have personal power. With changes in society and the workforce, managers are relying less on position power and more on personal power to influence followers and they are open to be influenced by followers with personal power. So, this shows that it is more beneficial for leaders to have both position and personal power.
