The interesting question about work is not why people do it. People do it because they need money, and any theory that has to be elaborate about this is a theory that has lost sight of the rent.
The interesting question is why so many of them do more of it than they are paid for. The Trades Union Congress publishes an estimate each year of unpaid overtime in Britain, and for as long as I have been paying attention the number has run to several million people doing several hours a week, worth tens of billions of pounds annually to their employers. That is not a fringe phenomenon or a story about a few driven executives. It is a teacher marking on Sunday evening, a nurse staying forty minutes past handover because the relatives have arrived, a solicitor reading a bundle on the train, a warehouse team leader coming in on their day off because the agency staff are new.
None of these people is confused about the transaction. Ask them and they will tell you that they are not being paid for it, that they resent it about half the time, and that they will do it again next week. Whatever accounts for that is what the psychology of motivation is actually about, and no theory that reduces to incentives will reach it.
The equal and opposite phenomenon is the one organisations complain about. Somewhere in the same country, someone who was that person four years ago now leaves at five past five, declines the extra shift, does exactly the specified task and no more, and is described by their manager as having disengaged. Nothing about their contract has changed. Their pay may well have gone up. What has changed is a relationship, and the vocabulary available to their manager for describing it — engagement, attitude, negativity — locates the change inside the employee, where it did not happen.

GPT-5.6 Sol:
The passage is making a fairly precise move: it shifts the problem of work motivation away from labour-market participation and toward discretionary effort. That is a much more productive question for occupational psychology.
‘Why do people work?’ is usually not very mysterious at the level of entering employment. Income, material security, and the institutional fact that most adults have to sell labour explain a great deal. But once somebody is already employed, the psychologically interesting variance is elsewhere: why do two people on essentially the same contract contribute very different amounts of attention, care, initiative, flexibility, emotional labour, and time?
The passage’s real subject is therefore the gap between the employment contract and the actual labour supplied.
A contract can specify hours, duties and remuneration, but it cannot specify exhaustively what competent performance requires. A teacher can technically stop preparing when the paid hours end; a nurse can complete the formal handover without spending another half-hour reassuring a family; an office worker can answer exactly the questions assigned and never notice the problem nobody has formally given them. Organisations rely heavily on behaviour that cannot easily be written into a job description.
Occupational psychology has several names for pieces of this territory: organisational citizenship behaviour, contextual performance, extra-role behaviour, discretionary effort, work engagement, prosocial motivation. Industrial relations has an older and in some ways sharper concept: the effort bargain. An employee does not simply sell a fixed quantity of ‘effort’ in the same way that somebody sells a tonne of steel. The employment relationship purchases control over someone’s labour for some period, but how intensely, conscientiously and imaginatively that labour is performed remains partly indeterminate.
That indeterminacy is where much of management happens.
The strongest claim: effort is relational
The final paragraph is the most important part. The employee who once volunteered and later becomes strictly contractual has not necessarily undergone some mysterious deterioration of character. Something may have happened between employee and organisation.
That maps closely onto the literature on the psychological contract. Alongside the legal employment contract, workers develop beliefs about reciprocal obligations:
I will stay late when things are difficult; you will treat me fairly.
I will make the organisation’s problems my problems; you will not treat me as disposable.
I will tolerate occasional inconvenience; you will not make the inconvenience permanent.
These terms are rarely explicit. But they can be extraordinarily powerful.
Suppose an employee repeatedly works late because the team is understaffed. For a while they may understand this as reciprocity: we are all helping each other through a difficult period. Then management freezes recruitment, awards senior executives bonuses, and begins treating the extra hours as normal. The observable behaviour may change abruptly: the employee starts leaving at 5.05.
Nothing economically obvious has to change. Salary may remain identical. Yet the employee has reclassified the relationship.
Previously:
‘This organisation deserves something from me beyond the minimum.’
Afterwards:
‘This organisation will receive exactly what it purchases.’
That is not simply ‘motivation falling’. It is the withdrawal of a previously extended gift.
And calling the resulting behaviour ‘disengagement’ can indeed obscure causality. The term describes the employee’s present psychological state while saying nothing about how it arose. In some organisations this becomes almost ideological: organisational conduct is translated into employee pathology.
Management does something → employee revises their effort → management diagnoses an ‘attitude problem’.
The passage is strongest when exposing that asymmetry.
But ‘unpaid overtime’ bundles together several different phenomena
The argument becomes weaker if every unpaid extra hour is treated as evidence of intrinsically or relationally motivated generosity.
People work unpaid overtime for many reasons, and some are barely voluntary.
There is a continuum:
Identification and care.
‘I want this lesson to be good.’
Professional obligation.
‘I cannot leave this patient halfway through something important.’
Solidarity.
‘If I leave now, my colleague gets buried.’
Reputation management.
‘I don’t want to be seen as someone who won’t help.’
Career incentives.
‘The people who stay late get promoted.’
Normative pressure.
‘Everybody here works past six.’
Workload impossibility.
‘The job cannot actually be performed within contracted hours.’
Fear.
‘If I don’t do this, I will be marked down or managed out.’
All of these can produce exactly the same observation: somebody works three unpaid hours.
Psychologically, however, they are quite different.
The teacher marking on Sunday might be displaying commitment to pupils. Or she might simply have been allocated a workload that makes Sunday marking unavoidable. The solicitor reading on the train may love the case, fear the partner, want promotion, or know that 1,800 billable hours cannot otherwise be achieved. The warehouse supervisor may feel loyalty to the new staff—or know what will happen to his performance metrics if they fail.
So the passage is right that a simple wage-incentive account is inadequate, but it occasionally risks interpreting structural compulsion as psychological motivation.
That distinction matters enormously. Otherwise an organisation can convert understaffing into evidence of employee commitment.
It also understates how broad ‘incentives’ can be
The sentence
‘no theory that reduces to incentives will reach it’
works rhetorically, but needs qualification theoretically.
If ‘incentive’ means direct marginal financial payment, then yes. An hourly wage cannot explain why somebody supplies unpaid labour after the compensated period ends.
But economists and psychologists can use ‘incentive’ much more broadly. Promotion prospects, reputation, reciprocal treatment, guilt avoidance, professional esteem, identity preservation and anticipated social disapproval can all affect behaviour.
At that point, however, the concept risks becoming unfalsifiable. If caring about a patient counts as an ‘incentive’, preserving one’s conception of oneself as a good teacher counts as an ‘incentive’, helping colleagues counts as an ‘incentive’, and resenting one’s employer while staying late anyway counts as an ‘incentive’, then saying ‘people respond to incentives’ explains almost nothing. It has simply renamed motives.
The more interesting analysis asks what kinds of motives exist, how they arise, and what organisations do to strengthen or destroy them.
Self-determination theory fits the passage particularly well
One useful framework is self-determination theory, because it distinguishes different qualities of motivation rather than simply high versus low motivation.
A person can do the same extra task because:
they are externally compelled;
they feel guilty if they do not;
they identify with its importance;
it fits deeply with their values;
they simply find the work satisfying.
Those motivational states predict very different experiences.
Two nurses may both stay forty minutes late. One thinks, ‘If I leave, the ward manager will make my life miserable.’ The other thinks, ‘That family needs somebody to explain what has happened.’
Behaviourally identical. Psychologically opposite.
This is why crude engagement surveys can be misleading. They tend to treat observable commitment as though it were a unitary quantity. But a workforce can exhibit high effort and terrible motivation simultaneously.
People can work extremely hard because they are frightened, ashamed, professionally trapped or chronically overloaded.
There is also an identity argument underneath the passage
Many occupations acquire moral identities.
A ‘good teacher’ prepares properly.
A ‘good nurse’ does not abandon a distressed family because the clock has struck seven.
A ‘good lawyer’ knows the bundle.
A ‘good manager’ does not leave inexperienced staff in trouble.
Once a standard becomes incorporated into someone’s identity, the employer acquires something extremely valuable: self-enforcing labour discipline.
The organisation no longer has to say:
‘You must stay another 40 minutes.’
The worker says it to themselves.
That is one reason professions built around care are especially vulnerable to unpaid labour. The employer can, deliberately or otherwise, exploit the fact that the worker’s ethical commitment is to the patient, pupil, client or colleague rather than to the employer.
A hospital may fail to staff adequately, but the nurse cannot retaliate against ‘the hospital’ without the immediate consequences falling on patients and colleagues.
The organisation therefore possesses a peculiar form of leverage: the worker’s conscience.
That point pushes the argument beyond ordinary motivational psychology and toward labour-process theory.
Reciprocity explains both halves of the passage
The unpaid-extra-effort worker and the 5.05 leaver are not necessarily two kinds of people. They can be the same person at different points in a reciprocal relationship.
A simple model would look like this:
Organisation provides:
pay + fairness + security + respect + competent management + reciprocity
Employee provides:
contractual labour + discretionary contribution
The second component on each side is partly contingent.
When workers perceive organisational support and fair treatment, they may reciprocate with extra-role behaviour. When they perceive injustice or psychological-contract breach, they may withdraw precisely those contributions that are easiest to withdraw.
Importantly, they may continue performing the formal job perfectly well.
That produces one of the conceptual problems with the contemporary expression ‘quiet quitting’. Much of what was described under that label was simply employees refusing to provide labour beyond contractual expectations. Calling that ‘quitting’ quietly embeds the managerial assumption that discretionary labour somehow belongs to the employer.
There is a revealing linguistic difference between:
‘The employee stopped going above and beyond.’
and
‘The employee became disengaged.’
The first describes a change in exchange. The second suggests a defect in the person.
Yet employees can misread the relationship too
The passage tilts deliberately toward correcting managerial attribution error, but the reverse error is possible.
Workers can form psychological expectations that the employer never accepted and could not reasonably satisfy. Someone might regard being passed over for promotion as betrayal even where another candidate was plainly stronger. They might perceive ordinary managerial oversight as distrust, or regard reasonable performance requirements as violations of autonomy.
Psychological contracts are subjective beliefs about obligations, not objective contracts.
That means ‘the relationship changed’ cannot automatically settle who caused the deterioration or whether anyone behaved wrongly.
An adequate organisational analysis has to distinguish:
actual breach from perceived breach;
procedural injustice from disappointment;
exploitation from legitimate reciprocity;
sustainable discretionary effort from compulsive overwork;
employee withdrawal from sensible boundary-setting.
Without those distinctions, ‘psychological contract’ can become as lazy an explanation as ‘engagement’.
There is a deeper paradox here
Organisations need discretionary effort, but they often destroy it by attempting to capture it.
A worker voluntarily gives 110%. Management observes 110% and redesigns the job around it. What was initially a gift becomes the baseline.
Then 110% stops being citizenship behaviour and becomes expected performance.
The employee experiences this as:
gift → expectation → entitlement → exploitation
while management experiences:
exceptional performance → demonstrated capacity → reasonable standard
That transition probably explains a substantial amount of organisational resentment.
It also produces an unpleasant equilibrium. Once workers learn that exceptional effort merely ratchets up expectations, withholding discretionary effort becomes rational self-protection.
The organisation has effectively punished generosity.
So the passage is really about the residual control problem
Its opening language makes this sound like a critique of theories of motivation, but underneath it is addressing one of the central problems of employment itself.
Employers purchase labour power but cannot completely purchase willingness.
They can buy someone’s presence for eight hours. They can specify outputs. They can monitor behaviour. They can create incentives and sanctions.
But there remains a residue:
How carefully will I do this?
Will I notice the problem nobody assigned me?
Will I help the new colleague?
Will I protect the organisation when nobody is watching?
Will I stay another twenty minutes?
Will I think about this problem on the train home?
That residue is economically enormous and contractually elusive.
Organisations therefore depend on psychological resources—trust, identification, reciprocity, professional pride, fairness, belonging—that they do not straightforwardly own.
And the central warning in the passage is that management frequently mistakes those resources for attributes of employees rather than properties of relationships.
That is the most compelling proposition in the excerpt. ‘Engagement’ sounds like something located inside Jane. But a substantial portion of what organisations call engagement may be better understood as Jane’s answer, continuously revised, to a relational question:
‘Given how this organisation treats me and the people I care about, how much of myself am I willing to give it?’
Once formulated that way, the employee who leaves at 5.05 is not the psychological opposite of the employee who once stayed until seven. Quite often, she is the causal sequel.
