When you get that promotion or that new assignment it comes with people, unless you are doing something brand new, starting from zero! Those people come with ways of working, ways of communicating, ways of thinking that they have developed over months and probably years. There is an existing trust with each other and with the organization. There is an existing level of commitment and accountability. And, there is an existing attention to detail and results. To some extent you are an outsider tasked with managing, leading and coaching these people.
From the time we first joined the workforce we’ve always done our best. We’ve put in the hours, done the work, worked hard to get somewhere. You’ve developed your skills, you’re good at what you do. Over time, people recognized your abilities! You may have won awards or received recognition for your effort in other ways. This was all based on your individual performance. You're a Rockstar now. Some in your organization may even believe you are ready to take on new responsibilities. They offer and change your job to one that manages people directly based on your previous Rockstar performance. You are now a first-time manager.
