In "ManagerOS: Upgrade Your Career" veteran executive Peter Badger shares 35 years of management experience from Wall Street to Silicon Valley. Unlike traditional management books that focus primarily on managing others, ManagerOS starts with the foundation of all effective leadership: managing yourself. This practical guide helps new and mid-level managers master five essential disciplines: Self-Management (optimizing your time, focus, and emotional control), Managing Up (building influence with superiors), Managing Subordinates (establishing credibility and motivating performance), Managing Teams (creating cultures of autonomy and accountability), and Managing Remote Employees (leading distributed teams effectively). Drawing from his experience scaling teams from 10 to over 300 people across startups, mid-sized companies, and global corporations, Badger delivers a blueprint filled with research-backed frameworks, real-world scenarios, and practical strategies. Whether you're newly promoted or navigating the challenges of middle management, ManagerOS provides the mindset and tools to help you thrive-not just survive-in today's fast-paced workplace.
