Preventative Mental Health Strategies for the Workplace
Preventative mental health is the practice of identifying and addressing the causes of poor mental health before they lead to more significant problems, such as sickness absence and disengagement, or before an individual reaches a crisis point.
As an employer, this means building a strategy that promotes mental health prevention at every level of the business, from organisational policy and culture to manager-level awareness and individual support.
This blog outlines this three-tiered framework, along with practical steps for building your strategy and measuring effectiveness.
What does preventative mental health mean at work?
Preventative mental health support aims to reduce the likelihood of mental health challenges progressing to a crisis point, or to catch warning signs early enough that low-level intervention is enough to show improvements.
It differs from reactive support in terms of timing, as reactive support is only used once an individual’s poor mental health has started to impact their day-to-day work and personal life.
Preventative mental health is typically broken down into three tiers:
- Primary prevention: Removing or reducing risk before it causes harm.
- Secondary prevention: Early identification and intervention.
- Tertiary prevention: Supporting recovery and reducing recurrence.
When considered in a workplace context, these tiers correspond to organisational design, manager awareness and capability, and individual access to support.
Why is mental health prevention just as important as crisis response?
The impact of poor mental health in the workplace is well-documented, with HSE statistics showing that stress, depression, and anxiety accounted for 52% of all work-related ill health in Great Britain in 2024/2025.
When mental health reaches a crisis point, the number of lost working days due to sickness absence increases, as does the need for formal HR processes to manage affected performance and costly recruitment to cover time off.
Preventative strategies allow for earlier intervention, where mental health challenges can be addressed by lower-cost provisions, reducing the risk of operational and financial impact.
Preventative mental health in the workplace: a three-tiered approach
A preventative approach works best when considered holistically, rather than as unconnected initiatives. Each of the three tiers below addresses a different level of the organisation, and success largely depends on the previous tier being in place first.
| Tier | Focus | Ownership | Example Actions |
| 1. Organisational foundations | Reducing structural and cultural risk factors | Senior leadership, HR, health and safety | Stress risk assessment, policy reviews |
| 2. Manager and team-level recognition | Spotting early signs and enabling conversation | Line managers, people teams | Manager training, team check-ins, signposting pathways |
| 3. Individual-level support | Accessing help before crisis point | Occupational health, clinical providers | Early therapy access, reasonable adjustments |
Tier 1: Organisational foundations
Effective mental health prevention depends on strong organisational foundations. Therefore, the first tier to consider covers the structural and policy-level groundwork that makes everything else possible.
This might include:
- Carrying out a risk assessment to identify root causes of stress (high work demands, low levels of control, poor relationships with colleagues, unclear responsibilities, big organisational changes).
- Investing in mental health consultancy to help uncover the root causes of poor mental health and areas for improvement in your current mental health strategy.
- Reviewing policies and health and safety procedures to ensure mental health is considered and embedded into them, where relevant.
Tier 2: Manager and team-level early recognition
Managers work closely with their team, putting them in a position where they are more likely to notice a change in an employee’s behaviour, workload, or level of engagement. Early recognition is central to mental health prevention, as it allows you to intervene early and mitigate small problems from becoming more significant.
Mental health training can help teach managers key skills for recognising early warning signs of poor mental health in their team, how to have supportive and confidential conversations about this, and knowing when it is appropriate to signpost an employee for further support.
Offering regular refresher training and organising frequent 1-1s with team members offers a more sustained approach and makes it more likely to normalise conversations about mental health before issues become urgent.
Tier 3: Individual-level support before crisis point
The third tier is about making sure employees can access appropriate support early, before initial symptoms start to escalate into larger issues. This can include options such as:
- Evidence-based therapies, such as Cognitive Behavioural Therapy.
- Counselling.
- Manager-led signposting to available resources.
- Specialist support for more complex problems.
How to build an effective preventative mental health strategy
Now that you understand what each of the three tiers are, what they involve, and how they interact, you can start to build a preventative strategy. Here are some tips for creating an effective preventative mental health strategy for your workplace:
- Carry out a stress risk assessment to identify where organisational risk currently sits.
- Review existing support against the three tiers to see where current provisions focus and where the gaps are.
- Train managers on early recognition and response and build in regular refresher sessions.
- Make early-access support visible by improving internal communication and manager signposting, so employees know what’s available before reaching a crisis point.
- Schedule regular reviews, for example annually, to reassess risk factors and update the strategy as the organisation changes.
How do you measure the effectiveness of a preventative approach to mental health?
Measuring the effectiveness of a preventative mental health strategy can be challenging, as its main aim is to avoid problems that would have otherwise happened. However, there are some useful indicators to keep track of, such as:
- Trends in sickness absences over time
- Trends in presenteeism over time
- Engagement survey results
- Manager confidence in approaching conversations about mental health
Sickness absences and presenteeism falling can suggest your workplace’s approach to mental health support is working, as can higher levels of employee engagement and manager confidence.
