Hi Samantha, This is a tricky one, as no company policy or procedure is in place. However, you do have some Regulations in which to help you. Firstly, you have the Health and Safety at Work Act 1974 (which is also quoted in the Management of Health and Safety at Work regs 1992) and I quote " Employees have a duty under section 7 of the HSW act 1974 to take reasonable care for their own health and safety and that of others who may be affected by their acts or omissions at work" From this, the employer has every right to remove the employee from his area of work, especially if there is a high risk / potential to cause harm, either to himself (employee), others and the workplace. I would suggest that alternative safe work is found for this employee (it has been known for people to be suspended from work altogether). It is then up to management to decide what to be done as regards his work but your responsibility would be to facilitate treatment either via his GP or other agencies. I know you said he doesn't wish management to know but you are also are an employee so you have responsibilities under the same Act. I think if this is dealt with sensitively, then the breach of confidentiality will be recognised as a necessary one. Perhaps some persuading on your part for you to disclose to key management? Hope this helps Roz Wood
