Update: Contingency fee capped at 1/5. New Jersey has a "no fault" clause in WC cases. It means that negligence or even willful culpability in workplace injury are not considered. Only the fact of the injury occurring on the job is what counts. That's normally limited to medical expenses or in some cases residual working capacity (partial disability). There's a sliding scale for partial disability and after having worked several such cases as mine, the lawyer deduced a possible payout of about $28k. Take 1/5 of that in the lawyer's fee and it's not even going to cover my living expenses for a year. Now, consider that when anyone files a workman's comp claim similar to mine, the employer doesn't need just cause to terminate employment.
Well, now you see why I decided to meet the lawyer before presenting my case to HR or RM. I'm not pursuing this any further. In this instance, They don't even have to know.
As for the overall attorney experience, I'd say he's handled this quite professionally. He didn't pump me up with any unrealistic expectations just to sign me up and start grabbing money for "incidentals", etc.
