Supporting Growth and Careers

Coaching Versus Directing was about the moment-to-moment craft of making someone better at the work in front of them. This page zooms out to months and years. Coaching answers “how do I help you do this task well?” Growth answers a larger question: “where are you going, and how does the work you do here move you toward it?”

People stay, and give you their best, when they can see a future worth working toward. This page shows you how to support that future without pretending you control it. Because here is the uncomfortable truth at the center of the topic: you cannot give anyone growth, and you often cannot give them a promotion. What you can do — reliably, deliberately — is create the opportunities that let people grow, and clear the obstacles in their way. That’s the job. This page teaches how to do it honestly.

The principle: growth is shared, but ownership is not split

The most common mistake managers make with careers is quietly taking on a job that was never theirs. They start to feel responsible for whether someone “gets ahead” — and then feel guilty, or make promises they can’t keep, when the organization doesn’t cooperate.

Here is the cleaner division of labor, and it holds in any organization:

   THE PERSON owns:              THE MANAGER owns:
   - where they want to go       - creating opportunities to grow
   - the effort to get there     - removing obstacles in the way
   - the choices along the way    - honest information about reality
                                  - advocacy where it's warranted

The person owns their career. It is their life, their direction, their effort. You cannot want it more than they do, and you should not try. What you own is the environment: the assignments you hand out, the introductions you make, the feedback you give, the blockers you clear, and the truth you tell them about where they actually stand. You are not the driver. You are the one who keeps the road open and the fuel flowing.

This division matters because it protects both of you. It stops you from over-promising (“I’ll get you promoted”) on something you don’t fully control. And it stops the person from treating their growth as something being done to them rather than by them — which is the surest way for it not to happen at all.

The common trap — owning an outcome you can’t deliver

The most damaging thing a well-meaning manager says is a version of “don’t worry, I’ll make sure you get promoted next cycle.” Promotions usually depend on budget, headcount, a committee, business results, and the performance of people you’ve never met. When it doesn’t happen, you’ve broken a promise and lost trust — over something that was never yours to promise. Own the inputs you control (opportunities, advocacy, honest feedback); never promise the outcome you don’t.

Stretch assignments: the real growth engine

Ask people what made them grow the most, and they rarely say “a training course.” They say things like: “I got thrown into running that project and had to figure it out,” or “my manager put me in front of the client when I wasn’t ready, but stayed close.” Growth comes overwhelmingly from doing real work that is slightly beyond your current ability — with enough support that you don’t drown.

That’s what a stretch assignment is: a piece of genuine, consequential work that sits a little past what someone has already proven they can do. Not so far past that they’ll fail and lose confidence; far enough that they can’t do it on autopilot.

The evidence — most development happens on the job

A widely cited rule of thumb in the development world, often called the “70-20-10” model, holds that roughly 70% of professional growth comes from challenging on-the-job experience, about 20% from other people (coaching, feedback, watching others), and only about 10% from formal training. The exact numbers are a heuristic, not a law — but the direction is well supported: people learn most by doing demanding real work with support, and far less by sitting in a classroom. Treat courses as a supplement, not the main event.

Why does stretch work when a course usually doesn’t? Because capability is built by struggle at the edge of ability, then reflection — not by absorbing information. A course tells you about running a project; running a real project, badly at first, then better, actually builds the muscle. The discomfort is the mechanism, not a side effect.

How to construct a good stretch

A stretch assignment isn’t just “give them something hard.” It has a shape:

• Real stakes. It has to matter — a real deadline, a real customer, real consequences. Make-work stretches nobody.
• Slightly beyond current ability. If they can already do it comfortably, it’s not a stretch, it’s just work. If it’s wildly beyond them, it’s a setup for failure. Aim for “they’ll have to grow into it.”
• Support scaled to the gap. The bigger the stretch, the closer you stay — a check-in, a named person to ask, a safety net for the worst case. Stretch without support is just abandonment.
• A named skill it builds. Both of you should be able to say what this assignment is for — “this is to build your ability to run a cross-team project,” not just “someone had to do it.”
• Permission to struggle. Say out loud that stumbling is expected and safe. If failure at a stretch is punished, no one will ever take one.

In practice — the ward and the warehouse

On a hospital ward, a charge nurse hands a capable but junior nurse the job of coordinating a complex discharge — normally the charge nurse’s own task. She doesn’t hand it over and vanish; she says, “You lead it, I’ll be at the desk, grab me if you hit anything you’re unsure about.” In a warehouse, a shift lead lets an experienced picker plan the next day’s pick routes for the first time — a supervisor’s job — reviewing the plan together before it goes live. In both cases it’s real work, slightly beyond reach, with the manager close but not hovering. That is the growth engine running exactly as designed.

The career conversation: direction first, then connect

You can’t tailor opportunities to someone if you don’t know where they want to go. That’s what a career conversation is for — and it is different from a normal one-on-one or a performance review. It is not about this week’s work or last quarter’s rating. It’s about direction, over a horizon of one to several years.

The structure is simple:

1. Understand the direction   →  "Where do you want to be growing toward?
                                   What kind of work energizes you?"
2. Get honest about now       →  "Here's where I see your strengths and gaps
                                   relative to that direction."
3. Connect today to there     →  "Given that, here's how the work in front of
                                   us can move you a step that way."

The first step is the one managers skip. Instead of assuming everyone wants to climb the same ladder you did, ask. Some people want to manage; many don’t. Some want depth (become the person who’s brilliant at one thing); others want breadth. Some want more responsibility; some want more balance for a season of life. None of these is wrong. You cannot support a direction you never bothered to learn.

Two things make this conversation work. First, ask open questions and actually listen — this is a coaching conversation, not a pitch (see Coaching Versus Directing). “What does a great next couple of years look like for you?” opens more than “Do you want to be a team lead?” Second, be honest about the present. Direction without an accurate picture of where they are today is a fantasy. If someone wants to lead but avoids every hard conversation, that gap is exactly the useful part of the talk — named kindly, it becomes the thing to work on.

Then you connect. This is where the manager earns their keep: taking the direction the person named and finding, in the real work of the team, the assignment or exposure that moves them a step that way. “You said you want to move toward client-facing work — I’d like you to run the next customer review. Here’s how we’ll prepare.” Now their day job and their future point the same direction.

In practice — a cafe and a career

A cafe owner has a barista who mentions, half-offhand, that she’d love to open her own place someday. Instead of nodding and forgetting, the owner starts small: lets her manage the supplier order one week, then the staff rota, then sit in on the books at month-end. None of it is a promotion. All of it is real experience pointed at where she said she wants to go. A year later she’s a far stronger employee — and, yes, closer to leaving. We’ll get to why that’s still the right call.

Growth is not promotion — keep them separate

Here is a distinction that saves enormous amounts of disappointment: growth and promotion are not the same thing, and conflating them poisons both.

• Growth is building capability — getting better, taking on more, mastering harder work. It is largely within your and the person’s control, and it can happen continuously.
• Promotion is a change in title and formal scope that the organization grants, usually because the business needs and can justify a person operating at a higher level. It depends on budget, structure, headcount, timing, and factors far outside your team.

Growth often leads to promotion, eventually — but not automatically, and not on a schedule anyone can promise. When you let people believe “if I grow, I’ll be promoted,” every growth conversation becomes a promotion negotiation, and every delayed promotion feels like a betrayal.

Keep them honestly separate. Celebrate and invest in growth freely, all the time. Be sober and precise about promotion: explain what a higher level actually requires, what the organization needs to see, and what is genuinely outside your control. You can be a relentless advocate for someone at promotion time while being scrupulously honest that you don’t hold the decision.

GROWTH                              PROMOTION
you and they largely control        the organization controls
can happen continuously             happens on the org's cycle/budget
about capability                    about title + formal scope
invest in it freely                 advocate honestly, never promise

The common trap — using “you’re growing” to dodge a promotion question

The flip side of over-promising is under-leveling. Some managers hide behind “you’re developing so well!” to avoid a straight answer about promotion — which people see through instantly and resent. Honesty runs both ways. If someone is genuinely operating at the next level and the block is budget or process, say so plainly and tell them exactly what you’re doing about it. Praise is not a substitute for a truthful answer.

”But if I grow them, they’ll leave”

This is the fear that quietly stops managers from investing in people, so let’s meet it directly. Yes — some people you develop will outgrow their role and leave, sometimes for opportunities you couldn’t offer. That is real, and it stings.

Now consider the alternative you’re implicitly choosing if you don’t develop people: a team of people who have stopped growing and therefore mostly stay. That is a far worse team. People who aren’t growing disengage, coast, and quietly lower the standard for everyone around them. You have optimized for retention and lost the thing retention was supposed to protect — a strong, motivated team.

There’s an old exchange that captures it. A finance officer asks, “What if we train them and they leave?” The manager answers, “What if we don’t, and they stay?” The second outcome — a room full of people who have stopped getting better but have nowhere else to go — is the genuinely dangerous one.

The honest reframe: your job is to make people so good they could leave, and to make your team a place worth not leaving. Do both. The growth is what makes them valuable; the environment — trust, autonomy, meaningful work — is what makes them stay anyway. And the ones who do leave, well developed and well treated, become your best sources of talent, referrals, and reputation for years. Developing people is not a leak in the bucket; it’s how you fill it in the first place.

The evidence — growth is a top reason people stay and go

Employee surveys across industries consistently place “opportunities to learn and grow” and “career development” near the very top of the reasons people give both for staying in a job and for leaving one — often above pay. The precise rankings vary by study and year, so treat any single number with caution, but the pattern is robust: a lack of visible growth is one of the most common drivers of quiet disengagement and eventual departure. Choosing not to develop people doesn’t keep them; it just changes how you lose them.

How it connects

Growth is where several earlier threads converge. It runs on the motivation engine of mastery — the deep human pull toward getting better at something that matters. Stretch assignments are simply delegation with a development purpose, and they require the same trust and autonomy to hand over real work. The career conversation is a coaching conversation aimed years out. And honest talk about where someone stands is only possible if you’ve been practicing performance management as a habit rather than saving all the truth for review day.

Try this

Pick one person you manage and, this week, have a fifteen-minute career conversation that is only about direction — not this week’s tasks. Ask one open question (“What kind of work do you want to be doing more of in a year or two?”) and mostly listen. Before it ends, name one real, slightly-beyond-them piece of work coming up that points that way, and offer it as a stretch — with the support you’ll provide. Write down, separately, one growth step (in your control) and one promotion factor (not in your control) so you keep them honestly distinct.

Reflect

1. For each person you manage, can you actually name where they want their career to go — or are you assuming they want the ladder you climbed?
2. When did you grow the most — was it a course, or was it hard real work at the edge of your ability with someone backing you? What does that tell you about how to develop others?
3. Have you ever over-promised an outcome (a promotion, a raise) that wasn’t fully yours to give? What did it cost when it didn’t land?
4. Do you treat growth and promotion as the same thing? Where has conflating them created disappointment for you or someone you manage?
5. Be honest: does the fear that good people will leave quietly hold you back from developing them? What is the team you’d have if you let that fear win?

Show reflections

1. Most managers find they’re assuming. The fix is cheap — a single open question, actually asked. If you can’t name someone’s direction, that’s not a character flaw, it’s a conversation you haven’t had yet.
2. Almost everyone answers “hard real work,” which is the whole case for stretch assignments over courses. The useful move is to take your own answer seriously and stop defaulting to “send them on a training” as your main development tool.
3. If you’ve done it, notice that the damage wasn’t the delay — it was the broken promise. The lesson isn’t to promise less growth; it’s to promise only the inputs you control and be honest about the outputs you don’t.
4. Conflating them turns every development chat into a promotion negotiation and makes ordinary delays feel like betrayal. Separating them lets you invest in growth generously and freely while staying scrupulously truthful about promotion.
5. The fear is real but the arithmetic is backwards. A team you refused to develop doesn’t stay strong and loyal — it stays and stagnates. The genuinely risky choice is the one that keeps people who have stopped getting better.
