Your career is too important to spend your time looking for a job on a variety of sites. If you were sick you would find the best possible doctor. You should do the same thing with your job site. There is no better job board in the world for legal professionals: LawCrossing shows you jobs from every single employer career page, job website, association website
Looking for a job when you're still working? It's tricky. Be careful of noticeable changes in your normal pattern. Don't take extra time off, come to work dressed better than usual, increase or decrease the amount of work you do, or go low profile if you've always been high profile.
