1.1 Managing risk
1.2 Sharing your risk assessment

Objective: That all employers carry out a COVID-19 risk assessment.
Everyone needs to assess and manage the risks of COVID-19. As an employer, you
also have a legal responsibility to protect workers and others from risk to
their health and safety. This means you need to think about the risks they
face and do everything reasonably practicable to minimise them, recognising
you cannot completely eliminate the risk of COVID-19.
You must make sure that the risk assessment for your business addresses the
risks of COVID-19, using this guidance to inform your decisions and control
measures. A risk assessment is not about creating huge amounts of paperwork,
but rather about identifying sensible measures to control the risks in your
workplace. If you have fewer than 5 workers, or are self-employed, you don’t
have to write anything down as part of your risk assessment. Your risk
assessment will help you decide whether you have done everything you need to.
The Health and Safety Executive has guidance for business on how to manage
risk and risk assessment at work along with specific advice to help control the risk of
coronavirus in workplaces.
Employers have a duty to consult their people on health and safety. You can do
this by listening and talking to them about the work and how you will manage
risks from COVID-19. The people who do the work are often the best people to
understand the risks in the workplace and will have a view on how to work
safely. Involving them in making decisions shows that you take their health
and safety seriously. You must consult with the health and safety
representative selected by a recognised trade union or, if there isn’t one, a
representative chosen by workers. As an employer, you cannot decide who the
representative will be.
At its most effective, full involvement of your workers creates a culture
where relationships between employers and workers are based on collaboration,
trust and joint problem solving. As is normal practice, workers should be
involved in assessing workplace risks and the development and review of
workplace health and safety policies in partnership with the employer.
Employers and workers should always come together to resolve issues. If
concerns still cannot be resolved, see below for further steps you can take.
Where the enforcing authority, such as the HSE or your local authority,
identifies employers who are not taking action to comply with the relevant
public health legislation and guidance to control public health risks, they
will consider taking a range of actions to improve control of workplace risks.
For example, this would cover employers not taking appropriate action to
socially distance, where possible. The actions the HSE can take include the
provision of specific advice to employers through to issuing enforcement
notices to help secure improvements.
How to raise a concern:

contact your employee representative
contact your trade union if you have one
contact HSE at:
