A year on from the new preventative duty landing, a familiar gap has opened up. Most organisations responded to the Worker Protection Act the way organisations always respond to new law: they updated the policy, ran an e-learning module, and filed the completion report. On paper, harassment prevention is handled. In the corridors, meeting rooms and messaging channels where harassment actually happens or gets stopped, nothing has changed. The duty is about behaviour. The response was about paperwork.
The Worker Protection Act 2023, in force since October 2024, requires employers to take reasonable steps to prevent sexual harassment, a preventative duty, not a reactive one. An e-learning module and an updated policy rarely satisfy it, because reasonable steps are judged on whether they are effective. Prevention is behavioural: managers who intervene, bystanders who act, HR that investigates well. That behaviour is built by rehearsal and proven by measurement.
What the duty actually asks for
The Worker Protection (Amendment of Equality Act 2010) Act 2023 introduced a positive duty on employers to take reasonable steps to prevent the sexual harassment of their workers. It came into force in October 2024, and it changed the question a tribunal asks. The old question was reactive: did you respond properly once a complaint was made? The new question is preventative: did you take reasonable steps to stop it happening at all? The direction of travel, through the Employment Rights Bill, is towards a still higher bar of all reasonable steps. Acas and the EHRC have both published guidance on what that looks like in practice, and you can read the Acas guidance on sexual harassment for the current position.
The critical word is reasonable, because it is judged on substance, not effort. A step that was cheap, box-ticking and ineffective is not obviously a reasonable one. A step that visibly changed how people behave is. That distinction is where the standard corporate response quietly fails.
Why the module does not clear the bar
An e-learning module produces one artefact: a completion rate. It tells you that a person sat in front of a screen and clicked Next enough times to reach the certificate. It tells you nothing about whether that person would now step in when a colleague is being harassed, challenge a senior figure crossing a line, or receive a disclosure without making it worse. Those are the behaviours the duty is really about, and awareness training has a long, well-documented record of not producing them.
This is not an argument against training. It is an argument against confusing information with capability. Telling people harassment is wrong does not equip them to act in the charged, ambiguous, fast-moving moment when it happens, any more than telling someone the theory of swimming keeps them afloat. The knowing-doing gap is the whole problem, and it is exactly where a policy PDF leaves people stranded.
What a reasonable step actually looks like
Some things cannot be taught, they have to be felt. Intervening when a senior colleague makes someone uncomfortable is one of them. It is frightening, socially costly and instinct-defying, and no slide prepares you for the flood of hesitation in the real moment. What prepares you is having already been there, in a rehearsal safe enough to fail in and real enough to matter.
That is the design behind our harassment prevention training. Trained actors play the moment out: the off-colour comment, the persistent unwanted attention, the manager who would rather not notice, and participants practise the actual behaviours, stepping in, naming it, supporting the person affected, until the response holds under pressure. Because it is behavioural, it can be measured at the level of what people do, not what they clicked, which gives an organisation genuine evidence of an effective reasonable step. For the wider context, our explainer on what workplace harassment is in the UK sets out the legal frame, and the same behavioural logic runs through why shouting and everyday aggression corrode a workplace long before anything reaches a formal complaint. None of it works without the thing the module skips: a genuine speak-up culture, where raising a concern is met with support rather than cost.
A completion certificate proves someone watched a video. The duty asks whether they would act. Those are not the same thing, and only one of them holds up.
The organisations that treat the harassment duty as a documentation exercise are exposed twice over: their people are no safer, and their compliance is no stronger. The ones that treat it as a behaviour-change problem, and prove the behaviour changed, are the ones that both protect their workers and meet the standard the law is moving towards. The duty was never about the PDF. It was always about the moment.
In Summary: The Harassment Duty Is Behavioural
The Worker Protection Act's preventative duty, in force since October 2024, requires reasonable steps to prevent sexual harassment, and reasonable is judged on effectiveness, not effort. An e-learning module and an updated policy produce a completion rate, not changed behaviour, and completion certificates are thin evidence at a tribunal. Prevention is behavioural: managers who intervene, bystanders who act, HR that handles disclosures well. That behaviour is built by rehearsal and proven by measurement.
- The duty is preventative, not reactive: the question is whether you took reasonable steps to stop harassment, with the Employment Rights Bill moving towards all reasonable steps.
- Reasonable is judged on substance, so cheap, ineffective, box-ticking steps are weak, and awareness modules rarely change behaviour.
- The behaviours that matter are intervening, challenging and supporting in the real moment, and no slide prepares people for them.
- Rehearsal-based training builds those behaviours and lets them be measured at Kirkpatrick Level 3, giving genuine evidence of an effective reasonable step.
Frequently Asked Questions
What does the Worker Protection Act require employers to do?
The Worker Protection Act 2023, in force since October 2024, places a preventative duty on employers to take reasonable steps to prevent sexual harassment of their workers. It shifts the obligation from reacting to complaints to actively stopping harassment before it happens, and the direction of travel through the Employment Rights Bill is towards an even higher all-reasonable-steps bar.
Does an e-learning module satisfy the harassment duty?
On its own, unlikely. A completion certificate proves someone clicked through a module, not that behaviour changed. Reasonable steps are judged on whether they were effective and proportionate, so a tribunal can look past the module to what people actually do. Awareness training that never changes behaviour is weak evidence of a real step.
How do you prove reasonable steps were taken?
By producing observable behaviour and a record of it. Rehearsal-based training measures whether managers intervene, whether bystanders act and whether HR investigates well, at Kirkpatrick Level 3. That behavioural evidence, logged over time, is far stronger proof of an effective reasonable step than a list of completion rates.
