grievance
It is important that if you feel dissatisfied with any matter relating to your employment you should have an effective means by which to raise such a grievance and, where appropriate, have it resolved.
Nothing in this procedure is intended to prevent you from informally raising with your manager any matter you may wish to mention. Informal discussion can frequently solve problems without the need for a written record. However, if you wish to raise a formal grievance you should normally do so in writing from the outset.
If you feel aggrieved at any matter relating to your work (except harassment, for which there is a separate procedure), you should first raise the matter with your manager, explaining fully the nature and extent of your grievance. You will then be invited to a meeting at a reasonable time and location at which your grievance will be investigated fully. You must take all reasonable steps to attend this meeting. You will be notified of the decision, in writing, normally within ten working days of the meeting.
