Random Drug Testing in the Workplace

Random Drug Testing In the Workplace

When we use the term ‘drug testing’, we are referring to the detection of drugs, or more correctly ‘the metabolites of drugs’, by way of analysing biological material. With alcohol testing being the exception, drug testing looks for the remaining chemicals known as metabolites, because drugs in the body typically break down very quickly. While urine testing is the most common form of testing in the UK, hair, saliva, and sweat can also be tested.

The Health and Safety Executive (HSE) and the UK Government both agree that there are certain sectors where security and safety are of critical importance, like those who drive public transport, the financial sector, the armed forces, the police, the nuclear industry, and the prison service, and that in these sectors workplace drug testing should be carried out.

How To Introduce A Drug Testing Policy In Your Company

It’s important to note that, while drug testing is legal, it’s not enforced by law. This fact should be stated in the company handbook or employment contract of any company who implements a workplace drug testing policy. Thus, any employee asked to undergo a drugs test must give their consent, keeping in mind that in some companies and some occupations, failure to give consent could result in a job applicant being refused a position in the company.

Make Your Drug Testing Policy Clear, Simple, Fair, And Consistent

Most companies who implement a drug testing policy do so because drug testing forms part of their Occupational Health & Safety programme. As mentioned above, this must be set out in your company handbook or employment contract. Your drug testing policy should clearly state your company’s views on alcohol and drugs, and specifically state your employees’ expected behaviour both in the workplace and out of the workplace while representing your company.

Your drug testing policy should answer the following questions:

  • Who will be conducting the tests, including how and where testing will be carried out;
  • What is your drug testing policy trying to achieve;
  • Should a drugs test prove to be positive, what disciplinary action will be enforced;
  • Should an employee fail a drugs test, what support will they be given, if any;
  • Who is your health and safety representative, and how can your employees find out more?

Your drug testing policy should clearly state that it’s unacceptable for any employee to attend the workplace whilst under the influence of alcohol and/or drugs. However, your comprehensive alcohol and drugs policy must ensure that these issues are addressed in an open, fair, and non-judgemental way.

How Should An Established Workplace Go About Implementing A Drug And Alcohol Policy

Drug testing in today’s workplaces comes in a variety of forms, including pre-employment testing, random testing, and post-accident testing. Some companies are against drug testing because they believe it could damage relations between employers and employees, as well as hinder both the recruitment and retention of good-quality personnel. Other companies, however, believe that drug testing in the workplace provides benefits of efficiency, safety, employee welfare, and the business’s good reputation. Companies with the strongest belief in drug testing are typically safety critical occupations, where intoxication due to drug taking could well increase the risk of accidents.

If you have now decided it’s time for your established business to implement a drug testing policy as part of your Occupational Health and Safety programme, use this opportunity to clearly convey to your employees the position you’re taking on drug misuse and your expectations of your staff regarding alcohol and drug use whilst they are employed by your company. Your existing contracts with staff members will need to be amended, with their approval. Once you have their approval, you now have consent to implement your alcohol and drugs policy. All personnel with such a contract should understand that they may be subjected to random drug testing, and that using drugs in the workplace, or being under the influence of drugs whilst in the workplace, can be a dismissible offence.

Additional Considerations When Implementing A Drug Testing Policy

When implementing a new drug testing policy in an established workplace, there are a few additional considerations worth thinking about:

Communicate Clearly — Make sure to thoroughly communicate the new policy to all employees. Explain the reasons for the policy, what drugs will be tested for, how testing will be conducted, and what the consequences are for positive tests. Be transparent and give employees opportunities to ask questions. Clear communication upfront will prevent confusion and pushback later.

Train Managers — Ensure managers and supervisors understand the policy details and how to enforce it properly. Train them on signs of impairment, how to handle employee questions/concerns about testing, and how to conduct disciplinary procedures if needed. Consistent and fair enforcement by managers is key.

Consider Employee Support Systems — A good drug policy does more than punish. Think about providing access to employee assistance programmes, addiction counselling services, or other support systems for those struggling with substance abuse issues. Show employees the policy aims to help them, not just discipline them.

Examine Company Culture — Take a hard look at company culture and norms that may contribute to unacceptable drug use. Overwork, high stress, poor work-life balance, boredom, and other cultural issues can factor into employee drug problems. Fixing culture weaknesses can reduce reliance on drug testing alone.

Keep Drug Testing Ethical — As much as possible, aim to conduct drug tests in an ethical manner respecting employee privacy and dignity. Arbitrary or vindictive testing erodes trust. Tests should always follow policy guidelines. Ensure proper care is taken in sample collection, chain of custody, and confidential result reporting to avoid accusations of impropriety.

Best Practices For Random Selection In Workplace Testing

Let’s tackle one of the trickiest parts of drug testing – keeping it truly random. While many companies claim their selection process is random, employees often doubt this. Here’s how to make your random testing programme bulletproof and fair.

Start by using specialised software rather than manual selection. You’ll want to document every step of your selection process – this isn’t just good practice, it’s your safety net if anyone challenges the fairness of your programme. Think of it like a lottery draw – everyone should have an equal chance of being picked.

We’ve seen companies fall into the trap of testing the same employees repeatedly while others slip through the cracks. To avoid this, track your testing patterns over time. If Bob from accounting has been tested three times while Jane from sales hasn’t been tested once, you might need to adjust your selection method.

Here’s a clever tip: consider splitting your workforce into groups based on risk levels. You might test safety-critical roles more frequently, but the selection within each group should still be random. Just make sure you’ve spelled this out clearly in your policy.

Remember – transparency builds trust. Share your selection process (minus the technical details) with your team. When employees understand the system is genuinely random and fair, they’re more likely to support it.

Random Drug Testing In The Workplace Must Be Fair And Carried Out With Dignity

When employers have consent for drug testing, typically when they have a full contractual Health and Safety policy included in staff contracts or staff handbooks, they must ensure that their reasons for testing are fair, that the testing is carried out under supervised conditions, and that the dignity of the person being tested is respected. In addition, the person being tested must also have been asked if they are currently taking prescription medication which might affect the testing results.

Companies must also ensure they stay up-to-date on government guidance or legislation that may have recently been introduced.

Businesses Operating In Certain Sectors May Have Higher Drug Testing Requirements

The drug testing requirements for businesses operating in certain sectors may need to be broader and more frequent, particularly those engaged in safety critical roles. Businesses operating in other European regions should check to ensure what the local restrictions might be at the testing location. Offshore civil and marine aviation should follow international guidelines.
