It sounds like things are on track seasider and, as predicted, a paltry settlement sum has been offered. Have you told them what you're prepared to settle for yet? Make it double what you have in mind and don't disclose that amount to anyone, even a solicitor working for you, as they are all mates outside the court and they have in mind what they want to settle for, too - it might not fit in with your requirements.
You can expect the process to continue and all documents have to be prepared ready for submission. The other side won't want all that hassle, so usually prefer a settlement to save more work. The more senior management you want to call in to the tribunal, the more likely they will be instructing their solicitor to get you off their backs so they don't have to attend - too costly and inconvenient.
The hint that no claim should be put in for costs of looking for another job indicates 'don't go to all that trouble - a cover-all payment should be made.' The one I have referred to was given the same advice i.e. 'you have given details that indicate your claim should encompass how much you have lost, too.'
The last one I was involved in set a date for 5 months hence, after the first small offer was refused. The judge said she wanted to see a settlement before the tribunal, so she could see there was a case for grievance. Then 3 months in, two offers came in a fortnight apart, so it got to 6 weeks before the tribunal date. The settlement was dealt with very quickly after that, and cheques were sent out on the last day of that month. Good luck - you're getting there!
