Hi - I highly recommend Sophie White from Abbiss Cadres. She helped me tremendously with my claim (maternity discrimination/unfair dismissal). I was hesitant to go the legal route, but felt the law (and my rights) and been ignored.
Sophie was incredibly knowledgeable and supportive. She is a mum as well, and was empathetic about the stress this situation was having on me and my family. She is also an excellent and skilled negotiator. I was going up against a very large company (and senior HR professionals and lawyers) and was so glad to have a very supportive partner in Sophie.
I was very impressed by the outcome we achieved and am so glad I hired Sophie.
I spoke to a few lawyers before hiring her, and have no doubt I made the best decision. Here are her details:

Whatever you decide, I hope it goes well for you.
