After being out of work for 2 years, you get a part time job. Just before you hit 2 months, you get an offer for a full time higher rate position from a firm you interviewed with before starting the part time job. So you give notice to the part time firm. After a month the new job lets you go.
Do you list those last 2 positions or go back to your old resume? My advice is to go back. If you list the part time job, mostly to use them as a reference, it can backfire because they might mention you left for another job. And you really don't want to list the last job because they said the reason to let you go was lower productivity. So extending the time being out of work seems to be less negative.
