From Teacher to HR Director

What I Didn't Expect — And the 5 Mistakes I Made Anyway

By Lisa Carr, The CompAlchemist  |  8-minute read  |  Career & Leadership

I led schools for 19 years. I ran classrooms, managed staff, navigated union negotiations, built culture from scratch, and sat across from unhappy parents. I thought I'd seen everything.

And I made five mistakes so fundamental, so embarrassingly avoidable, that I now think about them every time I sit across from a candidate trying to make a similar leap.

This is not a humble-brag about my resilience. This is a field guide — written for anyone pivoting into HR from education, social work, the military, or any other people-first profession who thinks their people skills are enough.

They're not. And that's okay. Here's what no one told me.

First: Why the Leap Made Sense — and Why It Was Harder Than It Looked

Teaching is one of the most complex leadership jobs that exists. You manage relationships, performance, conflict, budget constraints, legal requirements, and organizational politics — often simultaneously, often without support.

So when I made the transition into HR, I wasn't coming in without credentials. I was coming in with 19 years of lived, operational, relationship-intensive experience. I knew how to read a room. I knew how to deliver hard feedback. I knew what it felt like to be a frontline employee who wasn't being heard.

What I didn't know was how to speak the language of business.

And in corporate HR — particularly in Total Rewards and Compensation — language is everything.

If you can't connect people decisions to financial outcomes, if you can't make a case at the executive table in terms of risk, return, and revenue, you will be heard politely and then overlooked.

That was mistake number one. But we'll get there.

The 5 Mistakes — In the Order They Nearly Derailed Me

MISTAKE 01  I Led With Empathy When I Should Have Led With Data

In schools, empathy is currency. The moment you demonstrate that you understand someone's situation — a struggling teacher, an anxious parent, an overwhelmed student — trust follows. Empathy is the tool.

In corporate HR? Empathy is the context. Data is the tool.

I spent my first year in HR writing beautifully crafted employee relations memos, having deeply thoughtful conversations about how people felt about their compensation, and wondering why nothing was changing. The answer was uncomfortable: no one at the table was asking how employees felt. They were asking what it would cost, what the risk was, and what the benchmark said.

The pivot wasn't to stop caring — it was to lead with the number and follow with the story.

"We have a 7% gender pay gap at the manager level" gets you a meeting. "People feel underpaid" gets you a sympathetic nod and a closed door.

🔑 The Reframe:  Empathy is your differentiator. Data is your entry point. Use both — but know which one opens the door.

MISTAKE 02  I Didn't Know What I Didn't Know About Compensation

I understood pay in the way most educators do: salary grids, collective agreement rates, steps and lanes. Transparent, negotiated, codified.

Corporate compensation is a different world. Market pricing. Compa-ratios. Pay bands. Short-term incentives. Long-term incentives. Executive pay structures. The language was foreign, and for the first six months, I nodded along in meetings and Googled everything afterward.

Here's the part that stings: I didn't ask for help early enough. I was afraid that asking would expose how much I didn't know. So I learned slowly, through trial and error, instead of accelerating through mentorship and deliberate study.

The irony? In education, we celebrate not knowing. We call it a growth mindset. In corporate environments, we often perform confidence even when we're lost.

If I could go back, I would have found a mentor in Total Rewards within my first 90 days. I would have enrolled in a compensation certification programme immediately. I would have been direct: "This is new to me and I'm committed to learning it fast."

The gap between what I knew and what the role required wasn't a reason to hide. It was a curriculum to tackle.

🔑 The Reframe:  Name the gap. Build the plan. Nobody respects false confidence. They do respect self-aware urgency.

MISTAKE 03  I Underestimated the Difference Between Union and Non-Union Environments

I came from a unionized world. I knew collective bargaining agreements. I understood grievance procedures, seniority provisions, and the weight of a ratified contract.

What I underestimated was how differently HR operates without that scaffolding — and how much more discretion (and therefore accountability) lies with individual managers and HR practitioners in a non-union environment.

In a union environment, the contract governs. In a non-union environment, consistency, documentation, and defensible decision-making are your protection. Inconsistency doesn't just create employee relations issues — it creates legal exposure.

I also underestimated the reverse: clients who came from purely non-union corporate backgrounds who didn't understand the complexity of unionized workplaces. I assumed the knowledge was shared. It wasn't.

Today, I build every HR tool and resource I create to address both contexts explicitly. Because the gap between union and non-union practice is real, significant, and almost never discussed in mainstream HR content.

🔑 The Reframe:  Don't assume your audience shares your workplace context. The most useful HR resources speak both languages.

MISTAKE 04  I Waited to Be Given a Seat Instead of Building One

In education, authority is structured. You're a teacher, a department head, a vice principal, a principal. The hierarchy is clear, the progression is defined, and you earn your seat through formal advancement.

Corporate HR doesn't work that way. Especially not in Total Rewards.

The executives who command respect at the decision table don't wait for permission. They show up prepared, they speak in the language of the business, they bring recommendations not just problems, and they make themselves indispensable by connecting people decisions to business outcomes before anyone asks them to.

For two years, I prepared thorough analyses that I presented when asked. It took me too long to realize that the most effective HR leaders aren't reactive — they're predictive. They walk into the CFO's office before the budget cuts come and say: "Here's what I'm seeing, here's what it will cost us, and here's what I recommend."

That shift — from expert on call to strategic advisor — is the single most important career move I made. And it was years later than it should have been.

You don't get a seat at the table by being good at your job. You get it by making your job relevant to the table's agenda.

🔑 The Reframe:  Study the business. Learn the financials. Connect every people recommendation to a business outcome. Then show up uninvited — with answers.

MISTAKE 05  I Thought My Non-Linear Path Was a Liability

For years, I soft-pedalled the teaching background. I was afraid it would make me seem less serious, less corporate, less qualified. I would mention it briefly and pivot quickly to my more recent HR experience.

I was wrong. The teaching background is not a liability. It is the differentiator.

Nineteen years of leading people — diverse, challenging, under-resourced, high-stakes people situations — gave me a foundation that most people who came up purely through corporate HR simply don't have. I can walk into a room that's hostile, confused, or grieving, and I can hold it. I can give feedback that stings and have people thank me afterward. I can translate complex policy into language that a frontline employee can actually act on.

Those are not soft skills. Those are rare, high-value competencies. I just needed to stop apologizing for where I learned them.

The non-linear career path isn't a gap in your resume. It's the story that makes you interesting — and in HR, where every leader eventually has to build trust across an entire organization, interesting is an asset.

🔑 The Reframe:  Own every chapter. The winding road built the range. That's not a weakness to explain away — it's a credential to claim.

What I Know Now That I Didn't Know Then

The path from classroom to boardroom is not straight. It is not always smooth. And there will be rooms where your background gets you a second glance before it gets you respect.

But here's what that path gave me that I wouldn't trade:

▸    The ability to read the emotional temperature of a room before the first word is spoken.

▸    The confidence to deliver hard truths with care — and have them land.

▸    The credibility that comes from having been in the room where hard decisions actually affect real people.

▸    The instinct to build systems that work for the humans inside them, not just the auditors reviewing them.

▸    The knowledge that leadership is a practice, not a title — and that the best HR leaders are, at their core, teachers.

Your Monday Morning Move

If you're in the middle of a career transition — into HR, into Total Rewards, into any people function — here is the one thing I want you to do this week:

Write down the three skills from your previous career that you've been downplaying. Not hiding — downplaying. The ones you mention briefly before pivoting to something that sounds more corporate. Then write one sentence for each that connects it explicitly to a business outcome.

That's your positioning. That's your story. Stop apologizing for the path that made you who you are.
