I've got a major grievance with my boss, currently going though the process. However I've heard back from the hr rep, stating that I am only able to take a work colleague, the grievance is also about the colleagues so that's out, or a trade union, which I haven't got one. So my partner is unable to attend. Also with the grievance part of it means I am unable to leave to my house on my own due to major anxiety, so it's been suggested that it's at my house. I don't want my boss coming to my house, it hasn't got disabled access anyway which he needs. What can I do
