Herzberg's two-factor theory: hygiene factors and motivators

Frederick Herzberg's research, published as The Motivation to Work (1959) and popularised in his 1968 Harvard Business Review article "One More Time: How Do You Motivate Employees?", produced the single most counter-intuitive finding in management: the things that make people unhappy at work and the things that motivate them are not the same things.

The practical consequence is that most management effort aimed at motivation is misdirected.

The two factors

Herzberg and his colleagues interviewed around 200 engineers and accountants in Pittsburgh, asking them to describe times they felt exceptionally good and exceptionally bad about their jobs. The two lists barely overlapped.

Hygiene factors — present in the context of the job:

• Company policy and administration
• Supervision, and the relationship with the supervisor
• Working conditions
• Salary
• Relationships with peers
• Status and job security

Motivators — present in the content of the job:

• Achievement
• Recognition for achievement
• The work itself
• Responsibility
• Advancement
• Growth

Herzberg's claim is that these operate on separate scales. Hygiene factors run from dissatisfied to not dissatisfied. Motivators run from not satisfied to satisfied. Fixing hygiene gets you to neutral, and no further.

Why this matters more than it sounds

Almost every management response to poor morale is a hygiene response: refurbish the break room, adjust the policy, run an engagement survey, give a bonus. Herzberg predicts exactly what happens — a short-lived improvement, then back to baseline, and a manager concluding that "nothing satisfies them".

He also predicted that pay rises produce a brief effect and then become the new baseline, which most managers have observed and few have explained.

The theory does not say pay does not matter. Unfair or inadequate pay is a powerful source of dissatisfaction, and no amount of interesting work compensates for it. It says pay is the wrong tool for building motivation, and interesting work is the wrong tool for fixing unfair pay. Confusing the two — "we can't pay more, but we've given you a stretch project" — is a real and recognisable management failure.

Job enrichment: the practical prescription

Herzberg's answer was job enrichment — deliberately loading the job with motivators. He was careful to distinguish it from two things managers frequently mistake for it:

Concrete enrichment moves, none of which cost money:

• Remove a layer of checking so the person owns the output
• Give someone the whole task rather than a fragment of it
• Route feedback directly to the person, not through you
• Let someone become the recognised expert on something specific
• Give a new, harder task rather than more of the same one
• Recognise the achievement publicly and specifically

Applied in a UK workplace

A finance team of seven has high turnover among the purchase-ledger clerks. The exit interviews say "pay". The manager benchmarks the salary, finds it slightly below market, and gets a 4% uplift approved. Turnover improves for one quarter and then resumes.

Herzberg's reading: the pay was a genuine dissatisfier and fixing it was necessary. But the job itself — keying invoices, every one checked by a senior, no contact with suppliers, no visibility of the outcome — contains no motivators at all.

The enrichment version: each clerk takes ownership of a set of supplier accounts end to end, including query resolution directly with the supplier; the sample check replaces 100% checking once error rates are established; monthly figures are shared with the person whose accounts they are; and one clerk becomes the team's go-to for the new expenses system and trains the others.

Same headcount, same pay, materially different job. And note that the enrichment created evidence-generating activity — which matters if anyone in that team is working towards a qualification.

Criticisms and limitations

• Method bias. The critical-incident technique invites people to attribute good outcomes to themselves and bad ones to their circumstances. Some researchers argue the two factors are partly an artefact of that, and studies using other methods have not reliably reproduced the split.
• A narrow sample. Around 200 professionals in one American city in the 1950s. Extending that to shift workers, care staff or gig workers is a substantial assumption.
• Individual differences ignored. Herzberg treats motivators as universal. McClelland suggests people vary systematically in what drives them.
• Satisfaction is not performance. The theory addresses satisfaction; the link to productivity is assumed more than demonstrated.
• Pay is more complicated. Later research on fairness and equity suggests pay carries symbolic and status meaning that does not fit neatly into "hygiene".
• Enrichment is not always available. Some jobs are constrained by regulation, safety or technology. Telling a manager to enrich a role they cannot redesign is not useful advice.

How to evidence this in your ILM portfolio

Herzberg is unusually easy to evidence, because job enrichment produces visible changes you can document.

Level 3 — Unit 303 Managing the performance of others for motivating and managing performance, Unit 315 Developing a high performing team for building a high performing team, and Unit 304 Supporting wellbeing in the workplace where the change was about wellbeing. Suitable evidence:

• A reflective account of a motivation problem you diagnosed, what you concluded was hygiene and what was motivator, what you changed, and what happened
• Workplace documents — the revised role description, the team development plan, before-and-after turnover or absence data, survey results
• Witness testimony from the person whose role you enriched

Level 5 — Unit 503 Managing people, Unit 508 Managing operational workforce planning for workforce planning, and Unit 507 Leading and managing wellbeing in the workplace for wellbeing. At Level 5, evaluate: compare Herzberg with another motivation theory, say which better explained what you observed, and be honest about the constraints on job redesign in your organisation.
