Work stress is rarely “just one thing.” It’s usually a predictable mix of work design, leadership practices, team dynamics, and change pressures that builds up over time. There are organisational, team and individual factors to consider when assessing and addressing work stress and improving team’s mental health in your workplace.
When organisations ask what causes stress in the workplace, the most useful answer is: stress increases when job demands outweigh a person’s resources, control, clarity, and support, especially for sustained periods. That’s why the best solutions are both system-level (how work is designed and led) and skill-level (how people respond, communicate, and recover).
Many of the common workplace stressors outlined below are formally recognised in Australia as psychosocial hazards under Work Health and Safety (WHS) legislation. Under the Model Work Health and Safety Act and Regulations, employers (Persons Conducting a Business or Undertaking – PCBUs) have a legal duty to eliminate or minimise risks to both physical and psychological health, so far as is reasonably practicable. Safe Work Australia’s national guidance identifies hazards such as excessive job demands, low job control, poor support, conflict, bullying, role ambiguity, and poorly managed organisational change as psychosocial risks that must be proactively managed. This means workplace stress is not simply an individual wellbeing issue, it is a work health and safety responsibility. When psychosocial hazards are not addressed, they increase the risk of psychological injury, burnout, absenteeism, and workers’ compensation claims. When they are managed well, organisations see measurable improvements in safety, engagement, and performance.
Below you’ll find the top 10 causes of stress at work (common workplace stressors), plus practical ways to address them grounded in established frameworks (including the UK HSE’s core work stressors: demands, control, support, relationships, role, and change).
Quick snapshot: the “big 5” you’ll see in almost every workplace
If you only need 5 causes of stress in the workplace (or five possible causes of stress in the workplace), these show up again and again:
- Excessive workload and time pressure
- Low control / low autonomy
- Poor support (leader and/or organisational)
- Relationship conflict, bullying or sense of not belonging
- Role ambiguity and constant change
Do you relate to this list? Most people do! These are among the most consistent sources of stress in the workplace across industries, and they’re directly reflected in psychosocial risk guidance from major authorities.
The Top 10 causes of workplace stress (and what to do about them)
Unmanageable Workload and Time Pressure
What it looks like
- Constant urgency and sense of juggling
- “Everything is a priority”
- After-hours emails as the norm
- High performers quietly burning out
Workload is one of the most common workplace stressors across industries.
How to Address It
Organisation-level actions
- Conduct quarterly workload mapping by team.
- Align staffing levels with actual task volume.
- Eliminate low-value work (legacy reporting, duplicate approvals).
- Introduce realistic turnaround standards in consultation with relevant stakeholders..
Leader actions
- Ask weekly: “What needs to drop if something new comes in?”
- Publicly de-prioritise work when capacity is exceeded. Manage upwards and push back if needed.
- Model boundaries (no 10pm emails unless critical).
Employee actions
- Use a “Stop–Start–Continue” reflection monthly.
- Block 2 uninterrupted focus sessions per day.
- Clarify top 3 weekly priorities in writing with manager and be honest if expectations exceed capacity.
Implementation Tool: Capacity Audit
- List all major recurring tasks.
- Estimate realistic hours required.
- Compare to contracted hours.
- Remove, delegate, automate, or renegotiate 10–20%.
No resilience workshop will fix chronic overload. The system must change.
Low Control and Autonomy
Low autonomy increases stress even when workload is reasonable.
What it looks like
- Micromanagement
- Excessive approval layers
- No flexibility in scheduling or methods
How to Address It
Organisation-level actions
- Define roles clearly as well as decision-making authority.
- Introduce flexible work options where possible.
- Shift from activity metrics to outcome metrics.
Leader actions
- Replace “How did you do it?” with “Did we achieve the outcome?”
- Provide guardrails, not scripts.
- Ask: “Where do you want more ownership?”
Employee actions
- Proactively suggest a preferred workflow.
- Speak up if roles aren’t clear and negotiate decision boundaries clearly.
- Document agreed outcomes.
Implementation Tool: Autonomy Map
Create three columns:
- Decisions I own
- Decisions I influence
- Decisions I escalate
Clarity reduces stress instantly.
Role Ambiguity and Role Conflict
One of the most underestimated causes of workplace stress.
What it looks like
- Competing instructions
- Overlapping or removal of responsibilities
- Constant rework due to unclear expectations
How to Address It
Organisation-level actions
- Review and update position descriptions annually.
- Remove duplicate accountabilities.
- Clarify reporting lines during restructures.
Leader actions
- Define success metrics in measurable terms.
- Clarify “what good looks like.”
- Confirm scope boundaries.
Employee actions
- Write a one-page Role Charter.
- Clarify top 5 priorities.
- Ask: “What would exceeding expectations look like?”
Implementation Tool: Role Reset Conversation
Quarterly structured discussion:
- What are my 5 most important deliverables?
- What is no longer a priority?
- What will success be measured by?
Poor Leadership Support
Support buffers stress. Its absence magnifies it.
What it looks like
- No or few regular 1:1 meetings
- Only hearing from managers when something goes wrong
- Emotional and work-related concerns dismissed
How to Address It
Organisation-level actions
- Train leaders in psychological safety.
- Standardise 1:1 cadence.
- Hold leaders accountable for wellbeing metrics (this one is bold but strongly recommend this).
Leader actions
- Ask about workload and energy, not just output.
- Notice early warning signs (withdrawal, irritability, presenteeism).
- Validate before solving.
Employee actions
- Use structured language when asking for help:
- “Here’s the impact.”
- “Here’s what I need.”
- “Here’s what I propose.”
Implementation Tool: Green–Amber–Red Check-In
Weekly rating:
- Workload
- Energy
- Stress
- Support needed
Track patterns, not just snapshots.
Conflict, Incivility, and Toxic Behaviour
Interpersonal stress often gives rise to more psychological hazards at workspace than workload itself.
What it looks like
- Passive aggression
- Exclusion
- Repeated dismissive behaviour
- Avoided conversations
How to Address It
Organisation-level actions
- Clear behavioural standards.
- Transparent reporting pathways.
- Swift, fair investigations.
Leader actions

Implementation Tool: Team Charter
Define:
- Expected behaviours
- Unacceptable behaviours

- Escalation pathway
Culture, being a vital ingredient to the mental wellbeing and happiness of your staff, must be explicit, not assumed. That’s why you must do everything you can to build a positive workplace culture for addressing the root causes of stress.
Poor Communication and Information Overload
Stress rises when people don’t know what’s happening or are drowning in updates.
What it looks like
- Meetings without purpose or structure

- Low engagement
- “Just a job” mentality
- High turnover
How to Address It
Organisation-level actions
- Create clear development pathways and have budgets to support these.

Meaning is reinforced through repetition, and when aligned with values, investment in development and effective recognition programs..
Two mini case studies (what this looks like in real workplaces)
Case Study 1: “The high-performing team that’s quietly burning out”
A public-sector team we worked with recently consistently hits deadlines but sick leave has been rising and people are snapping at each other and reporting these incidents to their leaders. A quick stress scan showed:
- Demand overload (too many competing priorities)
- Low control (everything is urgent, approval-heavy)
- Role ambiguity (who owns what is unclear)
What we recommended that helped:
- A fortnightly capacity and priority reset (leaders + team)
- Role clarity one-pagers for each position provided annually
- New meeting hygiene rules and protected focus blocks
Within 6–8 weeks, the team reported fewer after-hours messages, clearer handoffs, and reduced conflict.
Case Study 2: “Change fatigue after a restructure”
A mid-sized organisation rolled out a new system while restructuring. Employees reported:
- Confusion about new expectations and the skills needed to use the system
- Anxiety about job security
- Reduced confidence in leadership messaging
What we recommended that helped:
- A Change Canvas published weekly (what’s changing, what’s not, top FAQs)
- Manager check-in scripts for consistent conversations, monitoring emotions and skill deficiencies
- Short skills sessions on stress regulation + communication
The biggest shift was psychological: people felt informed, supported, and less alone.
How our programs support these stress drivers (without band-aid solutions)
Leading Wellness Solutions programs are designed to reduce causes of stress in the workplace at both system and skill levels – leaders and employees – so improvements are practical and measurable. We have programs to suit most needs, and can also design and deliver bespoke programs based on a thorough needs assessment. Here’s some of our programs that make a big difference in workplace stress:
For leaders
- Working Well – builds leader capability to identify and prevent psychosocial hazards, reduce stigma, and improve culture.
- Flourishing Futures – practical frameworks to promote wellbeing initiatives and create a wellbeing action plan.
- Change Crafting – strengthens adaptive leadership through complexity and change.
- Authentically Aware – (leader-focused program listed) supports self-awareness and authentic leadership capability.
For all employees
- Stress Surfing – evidence-based stress management skills, including psychosocial hazard awareness.

If you’re looking to address possible causes of stress in the workplace comprehensively, the most effective pathway is usually a blended approach: leader workshop + employee seminar series + a simple action plan to lock in changes. We can also provide coaching to individuals and teams to assist with knowledge retention and meaningful action.
A simple next step: run a “Stress Hotspot” pulse (15 minutes)
We’ll leave you with a short team activity that can be very enlightening, very quickly. Ask teams to rate (0–10):
- Workload demand
- Control/autonomy
- Role clarity
- Support
- Relationships
- Change impact
Then ask: “What’s the one thing that would reduce stress most this month?”
That one question often reveals the real root cause of stress in the workplace and gives you a lead for what you can do next.
