Does happiness at work have a real impact on employee productivity?

- Two reference studies measure the same order of magnitude: around 12 percent more productivity in the University of Warwick lab experiments (2015), 13 percent in the University of Oxford study released in 2019 and published in Management Science in 2024.
- Both matter because they establish the direction of the relationship, where most workplace surveys only show a correlation.
- In the Oxford study the effect runs mostly through a better call to sale conversion rate, not only through a higher call volume.
- Happiness at work also lowers turnover, which counts: according to Deloitte (2018), it takes about two years for the performance reviews of an external hire to catch up with those of someone promoted internally.
- The backdrop is getting worse: in its State of the Global Workplace 2026, Gallup puts global employee engagement at 20 percent in 2025, its lowest level since 2020.
- Four levers to act on: recognise contributions, invest in wellness, ask employees what they need, and clarify roles and decision rights.
A company’s success relies, in large part, on how productive its workforce is. And if you want to inspire your employees to be more productive, one of the best things you can do? Try to make them happier.
Research has shown that happiness at work plays a huge part in employee productivity. According to a University of Oxford study first reported in 2019, employees are 13 percent more productive when they are happy. A 2015 University of Warwick study in the Journal of Labor Economics measured an effect of the same order, around 12 percent.
The backdrop, meanwhile, has got worse. In its State of the Global Workplace 2026, Gallup puts global employee engagement at 20 percent in 2025, its lowest level since 2020, and estimates the lost productivity at 10 trillion dollars, or 9 percent of global GDP. Engagement is not the same thing as happiness, but the two are measured on the same ground: in that same survey, 34 percent of employees say they are thriving, one point more than in 2024.
But how, exactly, are happiness and productivity linked? In what ways are happy employees more productive than their less happy counterparts? And what can organizations do to increase happiness at work and, in the process, productivity?
Happy employees work more efficiently…
One of the main connections between happiness at work and productivity is that happy employees are more efficient at completing tasks.
According to research from the University of Oxford, which surveyed telesales workers at a large telecommunications company, happy employees were able to make more calls per hour than unhappy employees. Or, in other words, employees were able to complete more tasks in a given time frame when they were happy.
…and drive better results
Not only were employees able to check more items off their to-do list when they experience happiness at work, they were also able to drive more results.
In addition to making more calls per hour, happy employees were also able to convert more of those calls into sales. So, during any given shift, happy employees weren’t just getting more done; they were actually bringing in more revenue to the company.
What the research actually says
Plenty of articles claim that happy employees are more productive without ever saying where the number comes from. Here are the three pieces of work that set the reference on this question, with their method and what they actually measure.
| Study | Year | Method | What it establishes |
|---|---|---|---|
| StudyOswald, Proto and Sgroi, University of Warwick (Journal of Labor Economics) | Year2015 | MethodLab experiments: mood is raised, then performance is measured | What it establishesSubjects made happier are around 12 percent more productive |
| StudyBellet, De Neve and Ward, University of Oxford (Management Science) | YearFindings released in 2019, paper published in 2024 | MethodWeekly administrative data on telesales workers at a large telecoms company, happiness tracked week by week | What it establishes13 percent more productive, with the effect running mostly through a better call to sale conversion rate |
| StudyGallup, State of the Global Workplace | Year2026 edition, 2025 data | MethodGlobal employee survey | What it establishes20 percent of employees engaged, the lowest level since 2020, and 34 percent who say they are thriving |
One clarification is worth making: most workplace surveys only establish a correlation. The two academic studies above are cited precisely because they go further. Warwick raised the mood of its subjects in the lab before measuring their performance; Oxford used the weather visible from the workstations, a shift in mood that owes nothing to the employee. In both cases the direction of the relationship is established: happiness drives productivity, and not merely success making people happy. The Oxford working paper announced in 2019 was published in Management Science in 2024.

Happiness at work reduces turnover
Happiness at work can also lower employee turnover. And the lower your turnover, the more productive your organization will be as a whole.
Lowering turnover increases productivity in a variety of ways. For example, when turnover is high, your organization’s human resources team has to spend a lot of time and energy recruiting for open positions. When you lower turnover, you free up that time and energy for your HR team to work on more important projects.
In addition, hiring new talent (instead of keeping existing talent in their roles or promoting them within the organization) can cause a drop in productivity, and that drop often lasts longer than you think. According to a 2018 Deloitte analysis, it takes about two years for the performance reviews of an external hire to catch up with those of someone promoted internally.
Bottom line? Employees that experience happiness at work are less likely to leave the organization. This lowers turnover, which helps support a higher level of productivity across the organization.

Tips for increasing employee happiness
Clearly, increasing happiness at work is a must if you want to foster more productivity in your organization.
But how do you do that? Here are four levers you can use to increase employee happiness, and productivity right along with it:
Recognize and appreciate your team
It’s hard to experience happiness at work if you feel like your hard work and contributions are unnoticed and unappreciated. In fact, according to O.C. Tanner, 79 percent of people who quit cite a lack of appreciation among their reasons for leaving.
So, if you want your employees to feel happier at work? Show them the recognition and appreciation they deserve.
The best way to recognize and appreciate your team will vary from employee to employee. For example, some employees might love to have their hard work called out during an all-hands meeting, while others find that kind of public appreciation overwhelming and prefer a quieter form: a thank you note, or a word in a one-on-one.
How you show your employees that you recognize and appreciate their hard work is up to you. But if you want your employees to be happier at work and more productive as a result? Just make sure that you’re celebrating their wins, recognizing their contributions, and showing appreciation for their hard work, and that you’re doing so on a regular basis.

Invest in employee wellness
Happiness and productivity go hand-in-hand with wellness. To really experience happiness at work and the productivity boost that goes with it, employees also need to feel healthy, both physically and mentally.
Employees are becoming more invested in their own wellness. In Aetna International’s 2020 Global Employee Health Study, which surveyed 4,011 employees, 89 percent rated their physical health and 84 percent their mental health as more important to them than a year earlier.
So, if you want your employees to be happier and more productive? Invest in their wellness.
Again, how you invest in your employees’ wellness will depend on your employees and your organization. Is your entire team working in the office? You might stock the kitchen with healthy snacks or bring in a yoga instructor to lead a weekly on-site yoga class and meditation. Do you have a fully remote team? Consider offering employees a wellness stipend to spend as they please. Does your workforce seem frazzled and overwhelmed? Consider overhauling your company’s policy around mental health days, and encourage your team to take time off when they need it.
When employees not only feel healthy, but feel that their company is invested in their health, it leads to higher levels of happiness and of productivity. The people who are slipping still have to be spotted in time: the signs of burnout show up well before the sick leave does.

Ask your employees what they need to be happy, and then give it to them
As an organization, you can try to figure out different ways to make your employees happier at work. But why not just ask them?
Survey your employees and ask them what they need to feel happier at work. Then (and this is the important part!), listen to their responses and, whenever possible, give them what they want.
For example, if your employees say that better benefits would make them happier, explore alternative benefits packages and give them the best one your budget allows. If employees ask for more flexible work options, do what you can to provide it, whether that means letting employees adjust their hours or moving towards a hybrid work environment and allowing employees to split their time between working from home and working from the office.

Clarify roles and decision rights
Happiness at work does not rest on perks and recognition alone. It also rests on knowing who decides what. An employee who is unsure where their role ends, who waits on an approval without knowing whose approval it is, or who redoes work already done elsewhere, spends their energy on organisational friction rather than on useful work.
The signal shows up among managers: Gallup reports that manager engagement fell from 27 percent to 22 percent between 2024 and 2025, the largest year over year drop recorded on that measure. This is not a problem of individual motivation, it is a problem of structure.
Clarifying roles, goals and decision processes removes a good share of that load. It is also the best defence against boreout, the boredom that settles in when a job has lost its purpose. Worth exploring: governance and role clarity.
And if employees ask for tools that empower them to do better work? Give them those tools, tools like Talkspirit.
Talkspirit is an organisational operating system built on three blocks: structure (roles, goals, governance meetings), collaboration (projects, tasks, shared documents) and communication (chat, newsfeed, home portal). Employees find the information without hunting for it, and know who to go to in order to move a decision forward.

FAQ
Yes, and the order of magnitude holds from one study to the next: around 12 percent more productivity in the University of Warwick lab experiments published in 2015, and 13 percent in the University of Oxford study released in 2019 and published in Management Science in 2024.
It tracked telesales workers at a large telecoms company week by week, matching their performance data with a weekly happiness report. Happy employees made more calls per hour and, above all, converted a higher share of those calls into sales.
A causal link, in these two specific studies. Warwick raised the mood of its subjects in the lab before measuring their performance, and Oxford used the weather visible from the workstations, a shift in mood that owes nothing to the employee. Most other surveys establish a correlation only.
It lowers it, and lower turnover supports productivity across the organisation. The HR team spends less time recruiting, and the company avoids the slowdown that comes with an external hire: according to Deloitte (2018), it takes about two years for their performance reviews to catch up with those of someone promoted internally.
Because a lack of it drives people out. According to O.C. Tanner, 79 percent of people who quit cite a lack of appreciation among their reasons for leaving.
Four levers: recognise and appreciate contributions on a regular basis, invest in physical and mental wellness, ask employees what they need and then act on it, and clarify roles, goals and decision processes, which is where most day to day friction sits.
