How do you know a new manager is struggling before it turns into a resignation?

You know a new manager is struggling when the way they talk about their own team changes: "we" becomes "they," check-ins get shorter or disappear, and small pieces of feedback start landing like personal attacks. None of that shows up on a scorecard. It shows up in conversation, weeks or months before anyone types up a resignation letter or a performance improvement plan.

Here's what I believe: by the time a struggling manager's situation reaches HR or a formal review, the actual moment to help them was already months in the past.

The tells show up in language before they show up in numbers

Listen to how a new manager describes their own team. Someone who's doing fine says "we" - we're behind on the project, we had a rough week, we figured it out. Someone who's struggling starts saying "they." They won't listen. They keep missing deadlines. They don't respect me. That shift from inside the team to outside it is one of the clearest early signals there is, and it costs nothing to notice. You just have to be listening for it in a normal conversation, not waiting for it to show up in a report.

A second tell: the check-ins get thinner. A new manager who used to bring you real problems starts bringing you nothing, or starts canceling one-on-ones because "there's nothing to update." That's rarely true. It usually means they've decided showing you a problem is riskier than hiding it, which tells you they don't feel safe enough yet to be honest about what's actually happening.

Watch for the swing between two extremes

Struggling new managers tend to land in one of two places, and both are worth watching for.

Some over-control. They start double-checking every piece of work that used to be trusted to someone else, rewriting emails their team already sent, sitting in on meetings they don't need to be in. It looks like diligence. It's usually anxiety wearing a work ethic.

Others go the opposite direction and disappear. They stop giving feedback, avoid the hard conversation that's clearly needed, and let problems sit because addressing them feels like more conflict than they can handle right now. It looks like trust in the team. It's usually avoidance.

Neither one is a character flaw, and neither one means someone is unfit to lead. Both are the same thing wearing different clothes: a person using whatever coping strategy is available to them under pressure they were never trained to handle. I wrote more about why that promotion itself sets people up this way in why good employees get labeled "bad managers", and the pattern here is the earlier version of that same story.

Feedback starts landing differently

Pay attention to how a new manager takes feedback on their own performance. Someone who's steady can hear "this didn't go well" and treat it as information. Someone who's struggling hears the same sentence as "you're bad at this," even when that's nowhere close to what was said. That's not oversensitivity for its own sake. A stressed nervous system processes a neutral comment as a threat more often than a regulated one does, which means the same feedback that used to land fine starts landing hard, and the person giving it often has no idea why.

If you notice a new manager getting defensive, going quiet, or seeming rattled by feedback that wouldn't have bothered them three months ago, that's not them getting worse at their job. That's a signal worth following up on directly, before it turns into someone deciding the safest move is to stop engaging with feedback at all.

Why nobody catches this in time

Most organizations only have one formal moment built in to check on a new manager: the annual review, sometimes a 90-day check-in if they're lucky. Everything described above happens in the gap between those moments, in a hallway conversation or a Slack message or a meeting where someone seems a little off. If nobody's specifically watching for it, it's easy to miss until it's already a resignation or a complaint from the team below them.

The fix isn't a new form or a longer review cycle. It's the manager one level up staying close enough, and asking directly enough, to notice the shift in language and tone before it becomes a pattern nobody can undo. "How's the team going" gets a rehearsed answer. "What's the hardest part of your week been" tends to get a real one.

What to do once you notice it

Once you see it, say something. Not a performance conversation, a human one: "I've noticed you seem a little more on edge lately, is everything alright with the team." That single question, asked without an agenda attached, does more than most formal interventions, because it tells the struggling manager that someone actually sees them instead of just their output.

From there, the work is building the skill nobody handed them when they got the title. That's the starting point for 1:1 leadership coaching, which begins with what's actually happening in someone's week before it gets anywhere near a new framework. If it's not one person but a whole layer of new managers showing the same signs, a leadership workshop built around real scenarios tends to reach more of them faster than waiting for each one to ask for help on their own.

It's also worth building the noticing itself into how a company promotes people in the first place, so a first-time manager has someone checking in on purpose during that first hard year, not by accident.

The real cost of waiting

My take: catching this early doesn't just save one manager's job. It saves the team underneath them, who feel every one of these swings, over-control and disappearing both, long before leadership does anything about it. And it saves the organization from writing off someone who might have been genuinely good at this, if anyone had noticed in time.

If you're seeing some of this in someone on your team right now, get in touch. The first conversation is just figuring out what's actually going on, before deciding what, if anything, needs to happen next.
