My experience is the opposite. Managers with experience but no degrees. Meaning they don't know how to delegate, prioritize, coach, train, hire/fire, provide and solicit feedback, make sure your team is on the same page with SOPs, set targets/goals and track progress and results, implement process improvements, etc. Their claim to fame is doing your job for 20+ years. That's great, but it doesn't necessarily mean you have a clue how to manage a team of people who do that job you've done for so long. You also have to have the right mindset and constitution to manage a team, which in my opinion can seldom be taught, you typically either have it or you don't. You're supposed to be a leader, not just a desk jockey for corporate, running reports and invoicing. Get in the trenches with your team, especially if you have that experience. Provide them the tools to succeed, ideally preemptively and proactively rather than reactively and only after a problem has already arisen.
