If the medical assessment proves positive, disciplinary action will be taken which will result in the immediate employee dismissal from MMC Limited.

The possession or consumption of alcohol or restricted drugs on the company or clients premises is strictly prohibited, and could render the employee liable to dismissal and prosecution under the act. Employees have a duty to inform the supervisor if they have been prescribed medication, which may affect their fitness to work (medical advice will then be sought).
