Most people talk about EA and Chief of Staff as a ladder, EA on the bottom rung, CoS somewhere above it. That framing gets a lot of talented EAs chasing a title that doesn't actually fit how they like to work. It isn't a ladder. It's a fork, and both directions are legitimate careers.
I've done both jobs. Here's the honest version of what each one actually rewards, so you can tell which fork you're standing at.
What EA work rewards
Being an excellent EA means being the person a principal can hand ambiguity to and trust it comes back resolved, on time, without a mess left behind. The satisfaction is real and specific: a calendar that runs without friction, an inbox that never buries something urgent, a trip that lands exactly as planned across four time zones. That's not "just admin." It's a genuine craft, and the people who are great at it are rare.
If you get real satisfaction from a day executed cleanly, from being the person who makes someone else's life measurably easier, that's not a lesser instinct than wanting to run strategy. It's a different one, and it's the backbone every functioning executive relies on.
What Chief of Staff work rewards
Chief of Staff work rewards something almost the opposite: comfort operating in a room before anyone has decided what's actually true yet. You're not being handed a clear task and executing it well. You're being handed an unresolved mess: two departments disagree, the board pack has no owner, the leadership team agreed on something in March that quietly died by May, and the reward is untangling it, often without the authority to simply order people to comply.
If you find yourself more energized by "nobody's tracking this and it's driving me crazy, let me fix the system" than by "this specific task is done and done well," that's the CoS instinct. It's not more virtuous. It's just a different kind of satisfaction.
A short self-diagnostic
Four honest questions, no right answer, just information about which fork actually fits you:
- When a day goes perfectly to plan, are you satisfied, or slightly bored? Satisfied points EA. Bored points CoS.
- When you spot a broken process, do you want to fix your piece of it, or redesign the whole system? Your piece points EA. The whole system points CoS.
- Do you do your best work serving one person deeply, or working across a whole leadership team? One person points EA. Across a team points CoS.
- When two people disagree and both outrank you, does that feel like a mess to stay out of, or a problem you want to resolve? Stay out of it points EA. Resolve it points CoS.
Most people aren't a clean sweep in one direction, and that's fine. What matters is the overall lean, not a perfect score.
The part nobody says out loud: fewer companies need a Chief of Staff
Here's the practical reality worth knowing before you chase the title. Every company with an executive needs a great EA at some point. Far fewer companies, at any given time, genuinely need a Chief of Staff: the role only pays for itself once an organization has reached a certain size or complexity. That doesn't make CoS the "better" career. It makes it a narrower market, with fewer openings, higher stakes, and, generally, higher pay to match the scarcity and the pressure.
Choosing EA isn't settling. Choosing CoS isn't automatically leveling up. They're different games, and the right one is whichever matches the four answers above, not whichever sounds more impressive on a business card.
