Where they differed most

The task — The grievance about the manager

Guidance excerpt: 'A fair grievance procedure normally follows these stages: the employee sets out the grievance in writing; the employer holds a meeting to discuss it without unreasonable delay; the employee has a statutory right to be accompanied at that meeting by a colleague or a trade union representative; the employer decides what action to take and confirms the decision to the employee in writing; and the employee is told they may appeal, with the appeal heard by someone not previously involved wherever possible. Written records should be kept at every stage.' Priya has submitted a grievance about her own line manager, Dean — who is the person who would normally hold the meeting. Using only the excerpt, set out the first 5 steps in order: exactly 5 bullets, one line each, no sub-points, no preamble. On the line where it matters, say what Dean's involvement changes and who should act instead.

* The employee sets out the grievance in writing.
* The employer holds a meeting to discuss it without unreasonable delay, but Dean's involvement changes this so someone not previously involved should act instead.
* The employee has a statutory right to be accompanied at that meeting by a colleague or a trade union representative.
* The employer decides what action to take and confirms the decision to the employee in writing.
* The employee is told they may appeal, with the appeal heard by someone not previously involved wherever possible.
- Priya sets out her grievance in writing.
- The employer holds a meeting without unreasonable delay; because Dean is the subject of the grievance, someone else from the employer should hold it instead.
- Priya is told she has the statutory right to be accompanied by a colleague or trade union representative.
- The employer decides what action to take and confirms the decision to Priya in writing.
- Priya is told she may appeal, with the appeal heard by someone not previously involved wherever possible.
