12.3 Leadership, People & Health and Safety Culture
Key Takeaways
Leadership accountability is legal as well as cultural: section 16 makes the chief executive officer responsible for the employer's duties, and section 8(2)(i) requires the employer to enforce health and safety measures.
Culture models such as Hudson's ladder (pathological to generative) and the Bradley curve (reactive to interdependent) help diagnose how an organisation thinks about safety, but they are diagnostic tools, not legal standards.
A just culture separates honest error, at-risk behaviour and reckless conduct, so people report mistakes while deliberate violations still lead to fair discipline.
Section 26 of the OHS Act forbids dismissing or disadvantaging an employee for giving information to an inspector, complying with an inspector's lawful direction, doing anything the Act permits or requires, or refusing to do something the Act prohibits.
Behaviour-based safety works only alongside engineering and management controls; blaming workers for unsafe acts without fixing the conditions that produce them repeats incidents.
1. Why People and Culture Are a Core Knowledge Area
The SACPCMP lists "People and Health and Safety Culture" as a core knowledge area for health and safety registration. Construction sites change daily, rely on many subcontractors and use a transient workforce, so written systems only work when supervisors and workers believe in them and act on them. The CHSM influences culture through leadership, communication, fair treatment and visible follow-through.
2. The Legal Basis for Leadership and Participation
Culture in South Africa rests on clear legal duties:
- Section 16 makes the chief executive officer responsible for ensuring that the employer's duties are properly discharged; delegating tasks under section 16(2) does not remove that responsibility.
- Section 8(2)(i) requires the employer to enforce the measures necessary for health and safety, and section 8(2)(e) requires the information, instructions, training and supervision necessary for safe work.
- Section 14 requires every employee to take reasonable care, co-operate, obey lawful health and safety rules, and report unsafe situations and incidents.
- Sections 17 to 20 give workers a formal voice through health and safety representatives and committees.
- CR 8 places named construction managers and supervisors in the line of accountability for site work.
Leadership commitment is therefore not optional. When a director says "safety first" but rewards only programme and cost, workers notice the gap between words and actions.
3. Models of Safety Culture
Several models help the CHSM describe where an organisation stands:
- Hudson's safety culture ladder (Patrick Hudson, building on Ron Westrum's work) has five levels:
- Pathological: "Who cares, as long as we're not caught?"
- Reactive: safety matters after every incident.
- Calculative: systems and statistics are in place, but driven by management.
- Proactive: the workforce helps find and fix problems before incidents.
- Generative: safety is how the business works, and bad news is welcomed.
- The Bradley curve (developed at DuPont) describes four stages: reactive (natural instinct), dependent (supervision and rules), independent (personal commitment) and interdependent (team members look out for each other).
These models are diagnostic tools. They help the CHSM decide on the next step, for example moving a calculative contractor towards worker involvement, but they are not legal standards and do not replace compliance.
4. Human Error and Just Culture
James Reason's work on human error distinguishes:
- Errors: slips and lapses (doing the wrong thing by accident or forgetting a step) and mistakes (a wrong plan or judgement);
- Violations: deliberate departures from rules, which may be routine ("everyone does it to save time"), situational (the right equipment is not available) or exceptional.
A just culture responds differently to each:
- Honest error in a well-designed system: console and learn, and redesign the task to make the error harder.
- At-risk behaviour, where a person drifts from the rule because the risk seems low or the system encourages shortcuts: coach the person and fix the system pressures, such as unrealistic programmes or missing equipment.
- Reckless conduct, a conscious disregard of a substantial and unjustifiable risk: take fair disciplinary action.
Just culture encourages reporting of near misses and mistakes, which is the information needed to prevent serious incidents.
5. Behaviour-Based Safety and Its Limits
Behaviour-based safety (BBS) programmes use the ABC model: Antecedents (triggers such as instructions or missing equipment), Behaviour, and Consequences (what happens afterwards). Peer observations and feedback can strengthen safe habits. However:
- BBS must not shift responsibility from the employer to workers; the employer's duties under section 8 remain.
- Unsafe behaviour usually reflects the conditions created by management, such as time pressure, poor planning, missing equipment or inadequate supervision.
- Higher-order controls (elimination, substitution and engineering) remain more reliable than relying on behaviour.
6. Protection Against Victimisation and Fair Discipline
Section 26 of the OHS Act forbids an employer to dismiss an employee, reduce their pay, worsen their conditions or disadvantage them because the employee gave information to an inspector or other person administering the Act, complied with an inspector's lawful direction, gave evidence in court, did anything the Act permits or requires, or refused to do something the Act prohibits. Workers who raise concerns, report incidents or co-operate with an inspection are protected.
Discipline for health and safety breaches must follow the Labour Relations Act, 1995 and its Code of Good Practice on dismissal: the rule must exist and be known, the employee must be given a fair hearing, and the sanction must be consistent and proportionate. Inconsistent discipline, such as dismissing a worker for not wearing a harness while ignoring the supervisor who sent them to work without anchor points, damages trust and may be unfair.
7. Practical Leadership Tools
The CHSM can strengthen culture with tools such as:
- Visible felt leadership: directors and managers walk the site, talk to workers about specific hazards, listen, and close out what they promised.
- Stop-work authority: a written site rule that any worker may stop a task they believe is unsafe without penalty, supported by section 26 protection and by CR 5(1)(q) and CR 7(1)(c)(viii) stop-work duties.
- Recognition: praise good hazard reports and safe practice, not only injury-free periods.
- Involving workers: include representatives in risk assessments, inspections and investigations.
- Supervisor development: supervisors set the daily tone; train them in task risk assessment, communication and fair correction.
- Culture surveys and perception interviews: anonymous surveys and structured interviews show whether management and workers see safety the same way.
8. Measuring Cultural Change
Culture changes slowly. Useful signals include more near-miss and hazard reports, faster close-out of worker concerns, active participation in committees, consistent discipline, and workers stopping unsafe work. A falling injury rate alone does not prove that culture has improved.
A steel-fixer reports to the health and safety representative that edge protection has been removed on the fourth floor, and the representative informs the visiting inspector. The next week the subcontractor's foreman moves the steel-fixer to night shift at a lower rate, saying he 'caused trouble with the Department'. What does the OHS Act say about this?
The move is only unlawful if the steel-fixer is a designated health and safety representative under section 17.
Section 26 prohibits disadvantaging an employee for giving information under the Act, so this is unlawful victimisation.
The foreman acted lawfully because section 14 obliges employees to report only to their employer, not to an inspector.
The action is lawful if the subcontractor pays the steel-fixer's previous rate for the first month on night shift.
An investigation finds that a scaffolder did not clip on while moving between lifts. Interviews show that the crew had been told to finish before a concrete pour, that only half the crew had double lanyards, and that supervisors had seen crews moving unclipped for weeks without comment. Using just-culture principles, how should the behaviour be classified and handled?
As a matter for the client only, because programme pressure was created by the pour date in the client's schedule.
As an honest slip requiring no action, because the scaffolder did not intend to fall.
As reckless conduct requiring dismissal of the scaffolder, because any departure from a fall protection rule is automatically reckless.
As at-risk behaviour shaped by system pressures: coach the crew, provide double lanyards, correct the programme pressure and address the supervisors who tolerated the practice.
A contractor's survey shows that management believes safety is a core value, but most workers say production always wins and that reporting near misses gets them blamed. Incident statistics are good. Using Hudson's culture ladder, which description fits best, and what is the most useful next step?
Pathological, because any gap between managers and workers means nobody cares; the next step is to replace the whole workforce.
Proactive, because managers believe safety is a value; the next step is to publish the statistics more widely.
Calculative at best, with systems and statistics driven by management; the next step is to involve workers, act visibly on their reports and stop blaming people for near misses.
Generative, because the statistics are good; the next step is to reduce the number of safety staff.
