The retainer likely provides a lien on any recovery. Thus, even if you recover money your attorney can claim they have a lien on the money for their contingency fee. Collecting on a judgment is not an easy do it yourself project. It is complicated. What I suggest is if you are unhappy with your attorney tell him or her and if that is not successful then retain new counsel to handle the collection stage.
Odds are your attorney is allowing sufficient time to pass so that your employer will not be able to simply walk back in and reopen the default judgment.
