First, I suggest you give things a second chance before firing your attorney for several reasons: (1) He/She may be doing more than you think but there's just poor communications; (2) He/She may not be doing anything because there's nothing yet to do, but there's poor communications to explain this to you; (3) You may have problems finding a replacement lawyer (see below) and/or (4) Letting your lawyer know you're unhappy might make the relationship work better than ever (the old "squeaky wheel" clichT)!
Second, you should know that, if you still want to get rid of your attorney, you don't need a reason. That's the good news, I suppose (if you've got a crummy one).
The bad news is that because fees are already so low in workers' comp. cases anyway, it gets harder and harder to find a second, or third, lawyer to take over your case. This is so because when your case ends, and the Workers' Comp. Judge approves the attorneys fees to be awarded, he/she rarely awards more than the standard 9 to 15% -- even though there may have been more than one lawyer handling the case!
So if you use 1 lawyer, he or she will usually be awarded 9-15% fees when the case ends. But if 2 lawyers worked on the case at different times, they'll probably have to SPLIT the 9-15% fees! Same if 3 lawyers are involved (3 into the same 9-15%!), and so on. How it actually works is that when your case ends, your then current lawyer contacts any previous attorney and works out a deal to split the 9-15% fees once the Judge awards it. [Occasionally (depending on the Judge and what area of the state and the details of your particular case), the Judge could award 15% or more in fees when there's been more than one lawyer involved in the case.]
Needless to say, it can be difficult finding truly competent workers' comp. lawyers who are willing to work on your case for, say, two-thirds or HALF of a measly 9 or 15% fee! So expect more than a few "You've got a good case but, sorry, no thanks."
One possible solution -- especially if you can't resolve serious complaints with your present lawyer -- is to approach your lawyer first and explain you'd
like to negotiate in advance what percent of the fee (if any) he/she intends to request since you'll be dismissing him/her. Try to get it in writing. That way, you can assure any prospective new lawyer how much of the fee to expect. [The lawyer usually won't negotiate in advance with you like this unless there's concern you might sue or file a complaint with the State Bar or such other ugly things lawyers like to avoid. But it's at least worth a try to ask, especially if you're having problems finding a new lawyer.] Naturally, if you can "persuade" your present lawyer to waive ALL his fees, it'll be much easier finding a replacement lawyer! [But don't count on an attorney waiving his entire fee, unless he/she REALLY feels guilty about doing a poor job for you -- or is just
glad to get rid of YOU!]
So the moral to this story is to try to pick your lawyer wisely the FIRST time around! (See Question #9 for a little help on this point.)
P.S. And if you fire your lawyer and ask for your file (and don't have a new lawyer taking care of this for you), your old lawyer CAN'T CHARGE YOU ANY FEES OR COSTS before returning your file! ALL fees and costs -- even copying and postage fees -- must still be approved FIRST by a Workers' Comp. Judge (usually, but not always, at the end of the case).
(And as for the last part of your question, even Satan wouldn't stoop to practicing workers' comp. law.)
