Hello my name is XXXXX XXXXX I am happy to help you today. I assume your employment has now ended from reading your question?
Ok so why is it that you think you only have 2 weeks to raise a claim?
Have you raised a formal grievance to your employer about your treatment?
Why did the union not forward the grievance?
Ok in the first place you should put the union on notice that you feel that they have failed in their duty to protect your position as a paying member and state that if you cannot get a remedy from the employment tribunal then you will consider bringing a professional negligence claim. If you have a grievance against the employer they should have forwarded it before now.
I do not know the reason why the union do not think you have a good case but they should have allowed your employer to hear your grievance.
I would suggest you submit a claim within the deadline to the employment tribunal to protect your position and also submit your grievance to the employer.
You should write on both documents that you had been seeking advice from your union which was not forthcoming which has lead to the late grievance.
The tribunal might agree to stay proceeding until your grievance can be heard.
Yes I think concilliation is a good idea in the circumstances.
You should answer the question that you have been asked and clarfiy the situation for them.
No they can refuse to represent you and you can equally say you do not want them to represent you. If they refuse though they will need to show they have good grounds.
You can represent yourself or engage a lawyer.
No problem and all the best with it. I would be grateful if you would take the time to rate my answer and do come back to me if you have further questions in the future.
