☕ Estimated time: a 3-min coffee break read
In my last article, we looked at what burnout actually is: an occupational syndrome, not a disorder, and certainly not a personal failure. This does not make it any less serious; burnout significantly impacts both mental and physical health. Mentioning the specific damage is beyond the purpose of this article, since I’m not trying to scare you. What we want is to prevent it, so each one of us understands how to empower ourselves to build a sustainable life.
And for this, we need to look under the hood.
To explain the mechanism of how burnout arises, I rely on a major theoretical model supported by research: The Job Demands-Resources (JD-R) model of Bakker & Demerouti.
Think of your job as a balance scale. According to JD-R model (2007), any occupation has two forces at play:
Job Demands
These are the physical, psychological, social, or organisational aspects of your work that require sustained effort. They aren’t inherently negative, but they come with a physiological and psychological cost. When these demands are high, prolonged, or poorly designed, they become work stressors that lead to exhaustion.
Examples of high demands:
- workload: simply having too much to do.
- role ambiguity & conflict: not knowing what is expected of you or being pulled in opposite directions.
- physical environment: poor or stressful environmental conditions.
- emotional demands: constant, taxing interactions with clients or colleagues.
Job Resources
These are the aspects of your job that support you in achieving your goals, reduce the impact of demands, and stimulate personal growth. They are instrumental; they spark your motivation and keep you engaged.
Examples of job resources:
- Organisational Level
- pay: fair compensation that reflects your effort and covers your needs.
- career opportunities: having a clear path for growth.
- job security: the peace of mind that comes from knowing your position is stable.
- Interpersonal & Social Level
- managerial support: having a supervisor who coaches you and provides the tools you need.
- a healthy team climate: an atmosphere of trust and psychological safety with colleagues.
- social support: having colleagues you can talk to or ask for help.
- Organising Work and Task Level
- participation in the decision-making: having a voice in the decisions that affect your work.
- autonomy & job control: having the freedom to decide how and when you complete your tasks.
- role clarity: knowing exactly what is expected of you and where your responsibilities end.
- feedback: receiving clear information on how you are performing and where you can improve.
- skill variety: the chance to use a range of different talents rather than doing the same thing over and over.
- task identity: being able to work on a project from beginning to end so you can see a visible outcome.
- task significance: the feeling that your work actually matters and has a positive impact on others.
The Burnout Mechanism: How the Scale Tilts
The relationship between these two is quite straightforward:
High demands require a high amount of mental and physical energy. Without a break, this leads to a depletion of energy.
High Demands -> Exhaustion
High resources motivate you, satisfy basic human needs, and increase performance.
High Resources -> Buffer Effect
Low resources lead to a cynical attitude and a sense of mental distance from your work.
Low Resources -> Cynicism
In other words, if your job is very demanding, the effort to fulfil it will naturally tire you. However, if your job provides high resources, you will be able to replenish that energy and work sustainably, without burning out.
High Demands + Low Resources => “Perfect” environment for Burnout
Beyond the Workplace: the Missing Piece of the Puzzle
Burnout is about a system that has run out of fuel. If the demands of your job are high, you must have high resources to survive it.
But what happens when the job doesn’t provide those resources? That’s where personal resources come in. In the next article, we’ll talk about your internal capital and how to build a reservoir of resilience.
