Many managers consider employees who are productive to work long hours, and even coming in early and leaving late is often appreciated.
However, research shows that the most productive employees are not those who work long hours because their ability to concentrate decreases. They find it difficult to complete work effectively, even slacking off even though they are always sitting in the office.
A 2020 study in Iceland of more than 2,500 workers found that productivity did not change or even increase when working hours were reduced from 40 to 35 hours per week. A similar study by Stanford University (USA) also showed that productivity dropped significantly after 50 hours of work per week. After 55 hours, productivity dropped so much that any overtime only produced poor quality results.
Many studies also show that on average, an employee only works most effectively for about three hours a day.
So working too many hours does not make for a more productive employee. The human brain needs periods of rest to increase concentration and cognitive function.
The second reason is that when employees work long hours leading to lack of sleep, they are more likely to make mistakes that affect work efficiency. Tired people will not concentrate and easily miss important tasks.
A report from the US Employment ServiceMyPerfectResumeshows that 88% of employees feel burned out at work. This can affect their productivity and overall health. Burnout makes it difficult for them to think clearly and make good decisions. This can directly hinder their productivity and ability to meet deadlines.
To be productive, employees need to have a balance between work and personal life. Time to relax with family or do things you enjoy is important to maintain mental and physical health.
Work-life balance statistics in the US show that 66% of employees say they do not have a good work-life balance. 48% say they are workaholics.
