To become completely exhausted from overwork or stress, losing all motivation.
To become completely exhausted and lose all energy or motivation, usually because of working too hard or being under too much stress for a long time. When someone burns out, they often feel unable to continue doing their job effectively.
Type
Inseparable
Collocations
burn out from stress — become exhausted from overwork
burn out at work — experience workplace exhaustion
feel burned out — the adjective form describing the resulting state
⚠️ Watch out
As a noun, 'burnout' is written as one word, but as a verb phrase it stays two words ('burn out') — this is a common spelling mix-up.

In the early 1940s, the British mathematician and codebreaker Alan Turing was at the center of one of history's most consequential intellectual efforts — breaking Nazi Germany's Enigma cipher at Bletchley Park. Turing worked at a pace that was extraordinary even among his brilliant peers, often going days with little sleep, {{obsessing|verb-various-tenses|medium}} over logical problems that others had abandoned. By 1942 and into 1943, colleagues noted that he had become increasingly {{withdrawn|adjective|medium}}, cycling compulsively between his billet and the hut, eating erratically, and struggling to engage with the institutional politics that were consuming Bletchley. He eventually {{stepped back|verb-various-tenses|hard}} from direct operational codebreaking leadership and moved toward more theoretical work on computing. Historians have noted that the sheer {{grinding|adjective|hard}} intensity of the war years — the stakes, the secrecy, the {{relentless|adjective|easy}} pressure — took a measurable toll on {{even|connective|medium}} his extraordinary capacity. {{So|connective|easy}}, the documented shift in Turing's role and demeanor during this period is one of history's clearest examples of what happens when sustained, high-pressure intellectual work is carried beyond what any person can maintain: {{indeed|connective|hard}}, even the most brilliant minds can {{burn out|phrasal-verb|medium}}.
To exhaust or wear (someone) out means to drain a person's physical and mental energy over time, usually because of relentless workload, long hours or sustained pressure. It describes a gradual depletion of resilience rather than a single moment of tiredness.
Type
Transitive verb phrase ('exhaust' + object / 'wear out' as a separable phrasal verb + object)
Collocations
exhaust employees — used when workload or pressure drains staff energy over time
wear out the team — describes a workforce reaching the point of fatigue after sustained demands
exhaust yourself — reflexive use, common in personal accounts of overwork
wear someone down — closely related expression emphasising a slow, cumulative effect
completely exhausted / worn out — common adjectival use describing the resulting state
⚠️ Watch out
'Exhaust' tends to describe the draining effect more directly, while 'wear out' emphasises a slower, cumulative process — the two are close but not always interchangeable. As a phrasal verb, 'wear out' is separable ('wear the team out' / 'wear out the team'), which 'exhaust' cannot do. Also note the adjectival form: 'exhausted' and 'worn out' describe the resulting state, not the action itself.

Renata had always been the person who said yes. Extra shift? Sure. Last-minute client call on a Saturday? She'd manage. For over a year, this was simply how she operated, and for a while it seemed to work.
Then came the quarter where three major accounts landed at once. The extra hours that used to feel manageable started to exhaust her in a way she hadn't experienced before — not just tired, but slow to recover, even after a full weekend off.
Her manager noticed before she did. During a routine check-in, he pointed out that she'd cancelled her last two days off and asked, directly, whether the pace was wearing her out. Renata admitted it was.
They restructured her workload the following week, moving two accounts to a colleague. It wasn't a dramatic fix, but it was enough. Within a month, she noticed the difference — she was tired at the end of a working day again, not exhausted by the middle of it.
WHEN "JUST PUSH THROUGH" STOPS WORKING: ONE MANAGER'S ACCOUNT
For nearly a decade, Tomás Ferreira prided himself on being the person his team could rely on, no matter how demanding the week became. "I used to think being exhausted was just part of the job," he says, speaking from the offices of the logistics company where he has worked for eleven years. "You push through, you catch up on sleep at the weekend, you carry on."
That changed two years ago, during a period he now describes plainly: "I was completely worn out, and I didn't recognise it until I was signed off work for three weeks."
Ferreira's account echoes a pattern occupational health specialists say they are seeing more frequently among mid-level managers — people caught between senior expectations and a team relying on them, with few visible off-ramps. "The hardest part wasn't the workload itself," he explains. "It was admitting that the workload had exhausted me before anyone else noticed."
Since returning, Ferreira has changed how he manages his own team, building in explicit checkpoints to ask whether anyone feels worn out before it becomes a crisis. "I'm not trying to eliminate hard weeks," he says. "I'm trying to catch the moment before hard weeks start to wear people down permanently. That's the part I got wrong the first time."
His company has since introduced mandatory quarterly workload reviews, a small but direct response to a problem many organisations still struggle to name early enough.
In professional contexts, to ‘experience burnout’ means to reach a state of physical, emotional and mental exhaustion caused by prolonged, unmanaged workplace stress. It typically describes an employee whose capacity has been depleted by sustained overwork rather than a single difficult period.
Type
Transitive verb + noun object (‘experience’ + ‘burnout’, functioning as a fixed professional expression)
Collocations
experience burnout — standard professional phrase describing reaching a state of work-related exhaustion
report experiencing burnout — common in HR surveys and wellbeing documentation
at risk of experiencing burnout — used preventively, before exhaustion becomes acute
prevent employees from experiencing burnout — used in policy and wellbeing documentation
signs / indicators of burnout — related noun phrase describing early warning signals
⚠️ Watch out
‘Burnout’ functions here as a noun, not a verb, so it is always paired with a verb such as ‘experience’, ‘report’ or ‘prevent’. Avoid treating ‘burnout’ as a verb on its own (‘she burnouts’) — this is not standard usage. The everyday phrasal verb ‘burn out’ remains correct outside formal written register, but the two should not be mixed within the same sentence.

Isabela had managed the onboarding team for just over two years when she first noticed the pattern. New hires were arriving faster than the team could absorb, and two of her most experienced coordinators had started missing details they would never normally overlook.
During a scheduled one-on-one, one of them admitted, quietly, that she had begun to experience burnout — not dramatically, but steadily, over the previous ten weeks. Isabela didn't dismiss it. She documented the conversation, raised it formally with HR the same afternoon, and requested a temporary redistribution of the onboarding caseload.
The response wasn't instant, but within two weeks a contractor had been brought in to cover the overflow. The coordinator who had spoken up later told Isabela that naming it directly — saying clearly that she was experiencing burnout rather than simply working through it — was what had made the difference.
Isabela now raises workload concerns earlier, without waiting for someone to reach a breaking point first.
REPORTED BURNOUT RATES PROMPT POLICY REVIEW AT MERIDIAN FINANCIAL SERVICES
Following the release of its annual workforce wellbeing survey, Meridian Financial Services has confirmed that a growing proportion of staff across its claims processing division report that they have experienced burnout within the past year — a figure that rose from seventeen to twenty-six percent since the previous cycle.
"We can no longer treat this as an individual performance issue," said Director of People Operations, Grace Ibhawoh, addressing department heads at a recent briefing. "When more than a quarter of a division reports having experienced burnout, that is a structural signal, not a series of isolated cases."
The division, which absorbed a substantial increase in claims volume without a corresponding rise in headcount, has been named in three of the past four quarterly wellbeing reviews. Staff turnover within the division has also increased by twelve percent year over year, with several departing employees citing sustained overtime during exit interviews.
In response, Meridian has committed to a phased hiring plan intended to bring staffing ratios back in line with claims volume by the end of the following fiscal year. A revised escalation protocol will also allow team leads to formally flag when a team member appears to be experiencing burnout, triggering an automatic wellbeing check-in within five working days.
Ibhawoh noted that the goal was not simply to respond once burnout occurred, but to intervene earlier: "The earlier we can identify a team member experiencing burnout, the more options we actually have.".
In academic discourse, to ‘reach occupational exhaustion’ means to arrive at a state of profound physical, cognitive and emotional depletion resulting from sustained, unmanaged occupational demands. The expression foregrounds exhaustion as the endpoint of a cumulative process rather than a transient experience of tiredness.
Type
Verb phrase (transitive: ‘reach’ + noun object ‘occupational exhaustion’, functioning as a fixed academic collocation)
Collocations
reach occupational exhaustion — standard academic phrase describing arrival at a depleted psychological/physiological state
approach occupational exhaustion — used to describe an earlier stage, before the state is fully reached
before reaching occupational exhaustion — common in preventive or intervention-focused academic writing
the point at which participants reached occupational exhaustion — frequent in empirical results sections
risk of reaching occupational exhaustion — used in predictive or risk-modelling contexts
⚠️ Watch out
Because ‘occupational exhaustion’ functions as a fixed, uncountable noun phrase, it should not take the indefinite article or be modified as though referring to a discrete episode (‘reached an occupational exhaustion’ is non-standard). Writers should also avoid conflating this expression with the general term ‘burnout’ without definitional justification, as reviewers in some disciplines treat the two as requiring distinct operationalisation.

Dr Femi Alonso had spent much of his early career studying resilience in high-pressure professions, and for a long time treated occupational exhaustion as something that happened primarily to others — a subject of study, not personal experience. That assumption unravelled during his second year directing a large multi-site research programme.
The workload had crept upward gradually: additional sites, additional reporting requirements, no additional staff. He noticed, almost academically, the same warning signs he had spent years describing in his own participants — declining engagement in tasks he once found meaningful, a growing sense of detachment from outcomes he had previously cared about deeply.
When a colleague gently suggested he had reached occupational exhaustion himself, Femi initially resisted the label. It felt, he later admitted, uncomfortably close to admitting professional failure. But reviewing his own data alongside his experience, he recognised the pattern precisely as he had documented it in others.
He restructured the programme's staffing model the following term — not only for his team, but as a direct response to what he now understood, from the inside, as a genuinely measurable process.
The Institutional Silence Around Reaching Occupational Exhaustion in Academia
Universities have long positioned themselves as institutions uniquely equipped to study psychological wellbeing, yet they remain notably reluctant to examine the conditions under which their own faculty reach occupational exhaustion. This asymmetry is not merely ironic; it is structurally significant. Academic career progression is frequently organised around metrics — publication counts, grant capture, teaching evaluations — that reward sustained, uninterrupted output, offering few institutional mechanisms for acknowledging when an individual has reached occupational exhaustion without simultaneously signalling reduced productivity or commitment.
Emerging research on academic labour suggests that early-career researchers are particularly vulnerable, often reaching occupational exhaustion within the probationary period preceding permanent appointment — precisely the juncture at which visible strain carries the greatest professional risk. The precarity of fixed-term contracts compounds this dynamic considerably, as disclosure of exhaustion may be perceived, rightly or wrongly, as jeopardising future employment prospects.
A growing body of scholarship argues that institutions must decouple the acknowledgement of having reached occupational exhaustion from judgements of professional competence. Doing so would require restructuring evaluation criteria to account explicitly for sustainable workload distribution, rather than treating exhaustion purely as an individual failure of resilience. Until such structural changes occur, the very institutions best positioned to study and address occupational exhaustion are likely to remain among the least equipped to recognise it within their own walls.
