Gaining Employee Consent for Drug Testing in the UK

Workplace drug testing is becoming more and more commonplace in the UK. In October 2014, the BBC reported that the amount of companies asking staff to take a drugs test had increased significantly over the last four years. So, why is this?

Who’s Being Tested?

Worker impairment due to recreational drug use is a hot topic in the UK. Outside of the country, it’s an even bigger issue now. In many countries, worker impairment is  causing headaches for employers as more countries pass medical and recreational cannabis laws. It is only a question of time before the UK will need to address these issues too.

Specific groups that are now being “targetted” for drug testing at work include,

The groups named above is just a small example of specific industry groups. It’s a taste of things to come. In the UK, you can be sure that workplace drug testing will touch every business in the next few years, without exception.

Random Drug Testing In The UK Workplace

Drug testing by employers is normally carried out on a random basis. Sometimes it is also required prior to employment, on suspicion of drug use, or on cause, following an incident or accident.

Because the drug testing of employees and prospective employees is a relatively new concept for many UK companies, many firms are unsure where they stand when it comes to asking staff to take a drug test, as they have no drug testing policy in place.

Employee Consent for Drug Testing

As the law stands now, employers need employee consent for drug testing. Often this will be covered in the employees’ contract or the staff handbook. This simple concept is complicated however by the fact that tribunals would normally expect employees to reasonably give their consent to undergo drug testing. In simple terms, an employee must have good grounds to refuse a drug and alcohol test. That is, they must be confident that the employer has requested the test irresponsibly or has been unfair.

Most employees are normally expected to reasonably give consent for workplace drug testing. Any worker who does not want to take a test should seek professional advice from their union or line manager. They should do this before refusing to give a test sample. However, pre-consent is often implicit in many contracts of employment. That is, the contract will include a clause agreement between the employee and employer agreeing drug and alcohol screening during the period of employment.

Workplace drug testing for employers

UK employers have a number of responsibilities:

  • They should only drug test where it is appropriate.
  • They must also be be fair in the implementation of the drug testing procedure.
  • Employers should operate testing in a fully random fashion. For instance, they must not to single out particular employees for drug and alcohol testing, unless this is justified by the nature of their jobs or their actions.

Workplace drug testing is far more common in safety critical employment roles. In these cases, testing frequencies may reasonably be far more frequent. There is no guidance in UK law regarding the frequency of random testing for specific employment roles.

Employees can not be forced or made to take a drug or alcohol test. If they refuse when the employer has good grounds to request a test, and has acted fairly and responsibly, then the employer can take disciplinary action.

Employers have a legal responsibility to ensure a safe workplace. As a result, this includes ensuring that no employee is undertaking employment under the influence of drugs or alcohol.

Checking The Premises Too

The scope of workplace drug testing can also involve checking the premises rather than the employee. This is also a useful way of picking up evidence that might give an employer greater authority to test a member of staff. An example of this would be the use of a cocaine drug wipe to check if an area has been utilised for drug usage. Similarly, a drug swab kit would check for all types of drugs in one sweep.

Workplace drug testing using a saliva drug screen

Most employers in the UK use a saliva or oral fluid drug test kit as a first line drug screening test. Such kits give instant, on-site results. We would consider this to be best first line drug test kit option.  This is because it it is minimally non-invasive, easy and safe to collect in front of the individual being tested, with observed sample collection. The Zoom Testing saliva drug test is a seven panel drug test that is considered to be an ideal combination drug test for employers in the UK.
