High demand-Low control

Karasek's High Demand-Low Control Model defines high stress, unhealthy jobs as those with low control and high demand conditions.

Low control conditions include de-skilled labour and reduced decision making autonomy. Employees in this position are not given the leeway to make decisions regarding their work or work environment. They also do not have the opportunity to learn new skills on the job or problem solve.

High demand conditions include inadequate time to meet job demands and excessive workload. When asked about their workload, employees in high demand situations often say, "I work very fast and/or hard," and, "There is not enough time to get the job done."

Karasek defines jobs and their associated stress levels by their particular demand-control combination (Schnall, 1998).


Karasek's Job Demand-Control Model

Karasek's Demand-Control Model

Karasek & Theorell (1990). Healthy Work: stress, productivity, and the reconstruction of working life. Basic Books, USA.

Active jobs, in the upper right quadrant, have high demands BUT also high levels of control. These challenging jobs lead to active learning and motivation to develop new behavior patterns.

High strain jobs, in the lower right quadrant, have high demands AND low control. These jobs have a high risk of psychological strain and physical illness.


The 4 psychosocial categories of work:

High Strain Jobs

stressed out faceThese jobs are defined by low decision making latitude, and high physical and/or psychological demands. The workplace is often rigid and inflexible in both environment and policy, thus workers are unable to take actions in order to control their environment and cope with the stress. As expected, these jobs lead to high levels of mental and physical illness among employees. Example jobs include garment stitcher, waitress, nurses aid, and mail worker.

Passive Jobs

bored faceThese jobs are defined by low decision making latitude, and low work demand. It often includes irrelevant, unchallenging, and unskilled work that is unsatisfying for the employee leading to apathy and boredom. These jobs also lead to high levels of mental and physical illness among employees. Example jobs include janitor, miner, and watchman.

Low Strain Jobs

relaxed faceThese jobs are defined by few psychological demands and a high level of control in the workplace. As expected, workers have higher than average levels of health and happiness. Example jobs include natural scientist, lineman, and architect.

Active Jobs

happy faceThese highly demanding jobs offer employees challenging work in environments of great flexibility and latitude. The ability to constantly learn new skills in an environment that provides the leeway to problem solve enables these employees to reduce levels of stress and maintain high levels of health. Example jobs include engineer, physician, and teacher.
