Northern has a very strict alcohol and drugs policy which must be adhered to at all times. All applicants must go through this process before an unconditional offer of employment can be made, as well as a pre-employment medical questionnaire.

Roles which are of a safety critical nature will need a more in depth medical examination to ensure that all of the medical standards are met. We can’t confirm your job offer until we are satisfied that you have met all of the relevant medical criteria.
