Managing drug and alcohol misuse at work

Workplace Drug & Alcohol Testing

1. Overview

Employers have a legal duty to protect employees’ health, safety and welfare. Understanding the signs of drug and alcohol misuse (or abuse) will help you to manage health and safety risk in your workplace, develop a policy to deal with drug and alcohol-related problems and support your employees.

What the issues are and what to look out for

Misuse is not the same thing as dependence. Drug and alcohol misuse is the use of illegal drugs and misuse of alcohol, medicines and substances such as solvents.

Consider these warning signs, which could indicate drug or alcohol misuse:

  • unexplained or frequent absences
  • a change in behaviour
  • unexplained dips in productivity
  • more accidents or near-misses
  • performance or conduct issues

These can also be signs of other things, like stress or illness.

2. Consult your employees

You must consult employees or their representatives on health and safety matters. Consultation involves you not only giving information to employees but also listening to them and taking account of what they say.

You could ask your employees what they know about the effects of drugs and alcohol on health and safety and the restrictions or rules on drug and alcohol use in your business.

3. Look at safety-critical work

Think about the kind of work you do and any safety-critical elements where drug or alcohol misuse could have a serious outcome, for example:

  • using machinery
  • using electrical equipment or ladders
  • driving or operating heavy lifting equipment

You can use this information to help with your risk assessment.

Where employees in safety-critical jobs seek help for alcohol or drug misuse, it may be necessary to transfer them to other work, at least temporarily.

4. Develop a policy

All organisations can benefit from an agreed policy on drug/alcohol misuse. You could include a drug and alcohol policy as part of your overall health and safety policy.

If an employee tells you they have a drug or alcohol problem, an effective policy should aim to help and support them rather than lead to dismissal.

But it should also highlight when you will take disciplinary or other action, for example that you will report drug possession or dealing at work to the police straight away.

There are examples of drug and alcohol policies in Health, work and wellbeing (PDF– an Advisory, Conciliation and Arbitration Service (Acas) booklet and Managing drug and alcohol misuse at work – a Chartered Institute of Personnel and Development (CIPD) booklet.

If you choose to use Screening and testing for drugs and alcohol, you could include that in your policy.

We offer a policy development service, so contact us for more information. 

Check and review what you have done

You should regularly check if your policy is working and whether you need to make changes.

5. Screening and testing for drugs and alcohol

Some employers have adopted screening as part of their drug and alcohol policy. If you want to do the same, think carefully about what you want screening to achieve and what you will do with the information it gives you.

There may be a case for screening, particularly in certain jobs (for example employees who make safety-critical decisions like drivers, pilots and some machinery operators). In jobs like these the misuse of drugs or alcohol could have disastrous effects for the employee, colleagues, members of the public and the environment.

Bear in mind that:

  • employees must consent to screening for practical and legal reasons
  • screening by itself will not solve problems caused by drug and alcohol misuse and, where introduced, should be part of a company’s overall health and safety policy
  • screening must be carried out properly to ensure samples cannot be contaminated or tampered with, and that testing procedures and analysis are accurate
  • employees can’t be made to take a test but, if they refuse when an employer has good grounds for testing, they may face disciplinary action

The Chartered Institute of Personnel and Development (CIPD) has more information on screening in their guide Managing drug and alcohol misuse at work.

6. Support employees with a drug or alcohol problem

When you’ve assessed the risk and have a policy on drug or alcohol misuse (or abuse) in your workplace, make sure your employees know about the policy and the support you offer.

Training and awareness

You could increase awareness by including an explanation of the drug and alcohol misuse policy in your induction process for all new employees.

You could also brief managers and supervisors so they are clear about:

  • how to recognise the signs of drug or alcohol misuse
  • the organisation’s rules on drug and alcohol misuse
  • what to do if they suspect an employee is misusing drugs or alcohol
  • what to do when an employee tells them about a drug or alcohol problem

We offer a awareness training tailored to your needs, so contact us for more information.

Support for employees

Employees with a drug or alcohol problem may ask for help at work if they are sure their problems will be dealt with discreetly and confidentially. But also consider your own legal position if you are given evidence or information that suggests an employee’s drug misuse has involved breaking the law at work.

Drug and alcohol dependence are recognised medical problems. Someone who is misusing drugs or alcohol has the same rights to confidentiality and support as they would if they had any other medical or psychological condition.

Encourage them to get help from their GP or a specialist drug or alcohol agency and refer them to your organisation’s occupational health service (if you have one).

Consider allowing someone time off to get expert help. Often the cost of recruiting and training a new employee may be more than the cost of time off.

Think about whether drug and alcohol misuse in your workplace is treated as a disciplinary matter or a health concern. If you dismiss someone because of drug or alcohol misuse without trying to help them, an employment tribunal may find that you’ve dismissed them unfairly.

But, if their normal work is safety-critical you may need to temporarily move them to another job.

Health advice and information

If you don’t have access to occupational health services, you can still support employees’ health and wellbeing. You can make sure there is information at work about where they can go for advice and help if they’re concerned about drug or alcohol misuse.

7. The law

You have a general duty under the Health and Safety at Work etc Act to ensure, so far as reasonably practicable, the health, safety and welfare of your employees. Employees must also take reasonable care of themselves and anyone who could be affected by their work.

There is up-to-date information on laws, such as the Misuse of Drugs Act 1971 and The Road Traffic Act 1988, which apply to drug and alcohol misuse. Frank also has useful information on the law.

    The manufacturer of the P3 Protect respirator has pledged to become Net Zero by 2030.
    In order to calculate their carbon footprint measurements they use the SME Climate Hub:

    They’re also graduates of the Climate Fit course, that helps SMEs reduce their carbon emissions and join the collective race to Net Zero.

    They monitor their own Scope 3 emissions as part of their carbon reduction plan. This includes their downstream supply chain. For example, transport, storage and distribution. Product end of life’ (downstream) measurement depends upon the method and the extent to which this is mitigated by closed or open-loop recycling and other factors.

    For ‘cradle-to-the grave’ carbon output, the factory is creating their own carbon reduction plan, including waste and everything else, to the point that a product leaves the factory gates.

    As a Cop26 Hero of Net Zero award winner, they are constantly looking at ways to limit their carbon footprint and continue as far as possible, without reliance on offset.

    Whatever emissions remain in the atmosphere are removed elsewhere.

    The manufacturer has signed up to Gold Standard, which is considered the best in the world. They offset the remainder of their carbon through the purchase of Gold Standard-certified carbon credits into sustainable projects around the world:
    They don't have larger company statutory reporting requirements, so are entering into the NHS supply chain with Evergreen, the Sustainable Supplier Assessment. This self-assessment and reporting tool shares sustainability credentials. They are currently tier 1 of 4 and working towards reducing emissions further.

    The sustainability narrative for manufacturing Net Zero PPE is underpinned by:

    • Sustainable design for manufacture, results in production and consumption patterns with the mantra "Reduce, Reuse, Recycle"
    • Reducing the amount of energy required to manufacture, use, clean and recycle products
    • Opting for renewable energy
    • Only using recyclable and/or reusable materials, including reusable and recyclable filters to limit material ending up in landfill

    An IVD Medical Device is defined in the IVDR as “any medical device which is a reagent, reagent product, calibrator, control material, kit, instrument, apparatus, piece of equipment, software or system, whether used alone or in combination, intended by the manufacturer to be used in vitro for the examination of specimens derived from the human body.

    In vitro diagnostics (IVDs) are tests that can detect disease, conditions and infections. In vitro simply means 'in glass', meaning these tests are typically conducted in test tubes, cassettes and similar equipment, as opposed to in vivo tests, which are conducted in the body itself.
