If you are tested at work, your employer should:
- have your written agreement to be tested for alcohol at work. This may be included as a term of your employment contract;
- have your written consent before each test;
- keep your medical records confidential;
- introduce a 'chain of custody' to make sure samples are not tampered with, are analysed by an accredited laboratory, and that appropriate action is taken if you test positive; and
- comply with the requirements of part 4.4 of the Information Commissioner's Employment Practices Code (PDF, 529KB), dealing with drug and alcohol testing.
The TUC has also produced guidance for reps on drug testing in the workplace.
