Can anyone recommend a Sheffield solicitor that is particularly good at say, writing grievance letters to an employer on behalf of an employee?

Cheers in advance! :)

search t'internet. you'll be surpirsed what you can find templates for.

Nice one Willman!

Why not join a union. Most have their own legal services section to deal with things like grievances etc.
You don`t have to tell your employer you are in one and you can have your subs taken out of your bank by direct debit.

also, if you have a car you may be entitled to legal advice as part of your insurance policy, even if it's not motoring related. worth a try?
