In addition, law firms have typically been more receptive to granting part-time status to an individual with a proven track record at the firm. Other professions, including the accounting profession, have been quicker to respond to the need for alternative work situations. I mention trends in other professions because the legal profession does tend to follow the pack on management issues. This of course does nothing to address your current situation.

Most firms believe that only certain types of work can be done on a less than full-time basis.
Some examples may include real-estate leasing, commercial lending, securities compliance, patent prosecution, licensing or tax advisory work. These are areas of practice that involve few last minute deadlines and more limited and predictable client contact. In your case, corporate is a hot practice area. But only certain aspects of corporate practice have predictable deadlines and clients that are not so demanding. These include commercial lending, corporate compliance, general corporate advisory, and, to some extent, licensing.
