How Unconscious Bias Affects Leadership Decisions in Construction

By Angela Hucker, Founder and CEO, EPIC

There is a moment that happens on every construction site in this country, several times a week, and almost nobody notices it.

A job comes up that is a bit of a stretch. Slightly more complex than routine, visible to the client, the sort of thing that will get noticed if it goes well. The supervisor has about four seconds to decide who gets it, while walking, while thinking about three other things.

He gives it to Dan.

Not because he has anything against anyone else. Not because he sat down and weighed it up. He gave it to Dan because Dan felt like the safe pair of hands, and Dan felt like the safe pair of hands because he is the one the supervisor pictures when he pictures someone doing that job.

That four seconds is where the conversation about bias in construction actually needs to happen. Not in a recruitment policy. Not in an annual module. There, on a Tuesday, in the four seconds nobody remembers afterwards.

1. Why bias training gets resisted, and why the resistance makes sense

Let me start with the objection rather than pretend it does not exist, because on a construction site it is usually the first thing said and it is rarely said politely.

Most unconscious bias training aims at attitudes. It is built on the premise that people hold hidden prejudices, and that surfacing them will change behaviour. Blokes on site pick that framing up immediately, correctly identify that they are being told they are secretly prejudiced, and do exactly what any of us would do when accused of something we do not recognise. They shut down, tick the box, and go back to work.

I have watched this happen for years and I do not blame the workforce for it. If your entire experience of a topic is being told you are the problem, disengagement is a reasonable response.

But the attitude framing is not just unpopular. I think it is largely aiming at the wrong thing.

Bias in construction leadership is not primarily about what you believe. It is about how you allocate under time pressure. It shows up in resourcing decisions, not in opinions, and it operates fastest in exactly the conditions this industry runs on: high pressure, low time, high stakes, and a supervisor making forty small calls a day on instinct.

Nobody promotes their prejudice. They promote the person who reminds them of themselves at that age, and they do it in four seconds, while thinking about something else.

“Bias does not only appear in recruitment. It operates through the hundreds of small leadership decisions that determine who is trusted, developed, heard and promoted.”

2. The eight decisions

Forget attitudes entirely for a moment and look only at decisions. Every frontline leader in construction makes these eight calls constantly, usually without registering them as decisions at all.

Who gets the challenging assignment. Who is trusted with responsibility without being asked to prove it first. Who gets mentored, and whose name you mention when someone more senior asks who is coming through. Who gets interrupted, and who gets listened to until they finish. Who receives direct, specific feedback, and who gets vague encouragement because you are worried about how they will take it. Whose mistake is treated as a learning moment. Whose mistake is quietly filed as confirmation they were never really up to it. And who gets flexibility when they ask for it, against who is judged for asking at all.

Not one of those requires you to hold a single prejudiced belief. Every one of them shapes a career.

The feedback one deserves particular attention, because it is the one well-intentioned leaders get wrong most. Withholding direct feedback from someone because you are unsure how they will receive it feels considerate. It is one of the most damaging things you can do to a person’s development, because they are the only one on the crew not being told how to improve, and in eighteen months the gap will be read as evidence of their limits.

3. The compounding loop

Here is the mechanism that makes all this matter, and it is the part almost never explained on a construction site.

A single allocation decision is trivial. One job, one Tuesday, no harm done. The problem is that these decisions are not independent. They feed each other, and after a few years the loop produces something that looks exactly like merit.

This is why the problem cannot be solved at the recruitment end. By the time someone is a candidate, the loop has already run for years. Fixing bias at the interview while leaving the daily allocation untouched is treating the symptom furthest from the cause.

4. What the industry data actually shows

When I interviewed 50 construction leaders for the EPIC Construction Leadership Report 2026, gender inequity and exclusion came up unprompted from 86% of them. That was not a question I asked. It was raised, repeatedly, by leaders across infrastructure, civil, commercial, energy and utilities, roughly half of whom were men.

One of them put the mechanism better than any framework I could offer.

“I’ve watched three good women leave in two years. Not because they couldn’t do the work. Because nobody dealt with the bloke making it impossible.”

Read that carefully, because it contains two separate failures. The first is the behaviour. The second, and the one that decided the outcome, is that nobody addressed it. That is a leadership decision, made repeatedly, by people who almost certainly did not think of themselves as part of a gender problem. They thought of themselves as busy.

Fewer than 3% of trade-qualified workers in Australian construction are women. We have run attraction campaigns for years against that number. It has barely moved, and it will not move while the everyday experience of the people who do arrive is shaped by the eight decisions above. I have written more about the specifics of that experience in Designed Without Her.

And this is not only a gender question. 68% of the same leaders raised migrant workers being underutilised. The mechanism is identical: instruction quality drops across a language boundary, the worker is judged on the outcome rather than the instruction, and a capable tradesperson gets categorised as someone who needs watching. That is an allocation loop too, and it is why clear expectations and bias are more connected than they appear.

Those four are usually treated as four separate industry programmes with four different owners. Look at them as allocation outcomes instead and they collapse into one problem, addressed on one work front, by one person, four seconds at a time.

5. This is a psychosocial safety issue, not a values poster

Construction has historically filed this topic under diversity, which put it in the same folder as the values statement and the annual report photo.

That filing is out of date. Discrimination, exclusion and harassment are psychosocial hazards under work health and safety law, with model guidance published by Safe Work Australia. Employers also carry a positive duty under federal anti-discrimination law to take reasonable and proportionate measures to eliminate sexual harassment and sex-based discrimination, with practical workplace guidance published by the Fair Work Ombudsman and by Safe Work Australia.

Positive duty is the phrase that matters. It does not mean responding well to complaints. It means taking action before anyone complains. A business whose entire approach is a reporting line is not meeting a positive duty, it is waiting.

Which means this belongs in the same conversation as any other site hazard: identified, controlled, and led by the person running the work front.

6. What actually works at the frontline

Awareness on its own changes very little. What changes allocation is friction: something small that interrupts the four second decision long enough for deliberation to occur.

Keep a list of who got the good jobs. Not a formal system. A note on your phone of who got the stretch assignments this quarter. Most supervisors who do this for the first time are genuinely surprised, and the surprise is the intervention. You cannot pattern-match on memory, because memory is exactly what the bias is running on.

Add three seconds before you allocate. Ask who else could do this with support. Not who is safest. Who could grow. Three seconds is enough to move a decision from reflex to choice, and it costs you nothing.

Give everyone the same quality of feedback. If you are softening feedback for one person on your crew, you are not protecting them. You are excluding them from development while telling yourself you are being kind. Direct and specific, to everyone, is the fair standard.

Run the swap test. If a different person had done exactly this, would I be having the same reaction, using the same words, at the same volume? It is uncomfortable to answer honestly and it is the fastest self-audit available.

Count the interruptions. For one toolbox talk, just notice who gets cut off and who gets heard out. You do not need to do anything with it on the day. Noticing is the whole exercise, and most leaders only need to do it once.

Deal with the bloke making it impossible. The quote above is the whole argument. If one person’s behaviour is driving capable people out, the failure that decides the outcome is not their behaviour. It is that nobody addressed it. That is a conversation, and it is yours.

What should change

1. Move the topic from attitudes to allocation. Stop asking people to examine their beliefs and start showing them their decisions. Allocation is observable, correctable and does not require anyone to confess to anything.

2. Train the frontline, not just the office. Bias training that reaches HR and senior leaders but not supervisors misses the layer where the eight decisions are actually made. EPIC RISE is built for the whole workforce, from apprentices and tradespeople through to site managers and executives.

3. Make the training adaptive rather than uniform. A one-size module teaches people things they already know while missing the gaps they actually have. EPIC RISE uses adaptive learning technology so a 20 minute module delivers a personalised path, and gives the organisation real-time visibility of where the knowledge gaps genuinely sit rather than a completion percentage.

4. Audit outcomes, not intentions. Look at who got the stretch work, who got mentored, who got promoted and who left, over twelve months. Intentions cannot be measured. Distributions can.

5. Stop separating this from leadership development. Fair allocation, honest feedback and addressing corrosive behaviour are not a diversity programme. They are what competent frontline leadership consists of, which is why this sits alongside delegation and psychological safety rather than in a separate folder.

Four seconds, forty times a day

I am not asking anyone in construction to accept that they are prejudiced. I do not think that framing is accurate and I know it does not work.

I am asking something narrower and considerably more useful. You make around forty allocation decisions a day, most of them in a few seconds, most of them on pattern recognition built from twenty years of what a capable person has looked like on the sites you have worked. That pattern was formed on a workforce that was almost entirely male, almost entirely local, and almost entirely like you.

It is not a moral failing that your instinct was calibrated on the industry you came up in. It would be strange if it were not. What is available to you is three seconds of deliberation before the instinct becomes an allocation, and a note on your phone that tells you the truth at the end of the quarter.

That is not a values exercise. It is workforce planning, and we are 300,000 people short.

Frequently Asked Questions

How does unconscious bias actually show up in construction leadership?

Through allocation rather than attitudes. Who gets the challenging assignment, who is trusted without having to prove it first, who gets mentored, who gets interrupted, who receives direct feedback, whose mistake is a learning moment and whose is filed as proof they were never capable, and who gets flexibility without judgement. None of those require a prejudiced belief, and all of them shape a career.

Why does unconscious bias training get resisted on construction sites?

Because most of it aims at attitudes, which workers correctly read as being told they are secretly prejudiced. Disengagement is a reasonable response to that framing. Reframing bias as how you allocate work under time pressure makes it observable, correctable, and does not require anyone to confess to anything.

What is the compounding loop?

A stretch assignment goes to whoever felt like the safe pair of hands. That person gains real experience, which becomes documented evidence of capability, which becomes reputation, which makes them the obvious promotion candidate. Every step is individually defensible and by the final step it is indistinguishable from merit, which is why fixing bias only at recruitment does not work.

Is unconscious bias a work health and safety issue?

Increasingly, yes. Discrimination, exclusion and harassment are psychosocial hazards under work health and safety law, with model guidance from Safe Work Australia. Employers also carry a positive duty under federal anti-discrimination law to take reasonable and proportionate measures to eliminate sexual harassment and sex-based discrimination, with guidance from the Fair Work Ombudsman. A positive duty means acting before anyone complains.

What can a supervisor do about bias tomorrow?

Keep an informal note of who got the stretch jobs this quarter, because you cannot pattern-match on memory when memory is what the bias runs on. Add three seconds before allocating and ask who could grow rather than who is safest. Give everyone the same quality of direct feedback. And notice, for one toolbox talk, who gets interrupted and who gets heard out.
