The only time I ever went back it was after being gone for 6 months. We started talking after I was gone 3 months and I told them what would be perfect for me. They I guess kept looking for my replacement and then gave me what I wanted. I was with that for about a year before new ownership came in and wanted a different deal. I was given a severance and had an even better job within a week! It worked out for me but the only reason I went back is because I wanted hourly and the ability to work contract gigs on top of having their insurance and a reliable pay.
