You may not have the arm (now recovered from rotator cuff surgery) but you may have the same dilemma: to retire or not to retire?

And, like the famously waffling QB, you may change your mind.

For the second summer in a row, Brett Favre, the holder of every major NFL career passing record reversed his decision to suit up for his rival The Minnesota Vikings, hoping to help them capture their first Super Bowl. After spending 16 years with Green Bay, Favre will face them on the line. Most Minnesota fans cheered but a few hissed and booed and promptly produced black t-shirts reading “Brett Who” and “What the Favre.”

Many baby boomers are finding themselves in the same metaphorical shoes as Favre, not sure whether they can–or want to– retire. We may just love the game of work, as does Favre, or we may not have saved enough in our 401ks but for whatever reason, we’re staying in the game long past what others think is our prime. They shouldn’t be surprised, as I write in my book Stop Pissing Me Off! What do do When the People you Work with Drive You Crazy, baby boomers have always changed the rules as we moved through the world of work, and it’s no different now.

Cynics may cry that it was the 12 million this year and the 13 million the next year (assuming he stays on the roster) that induced Favre to put on the #4 again, but he insists that he just didn’t want to look back and regret missing the chance to play one more year.

So what does this mean to you? If you’re a manager, don’t assume that someone’s going to retire or stay retired. All the studies show that boomers are going to be working longer, working part time and even pulling a Favre and returning. If you’re a worker, don’t burn your bridges. Leave your current employer wanting more, and maintain your network of contacts in case you need to find a new job.

And of course, work out that passing arm under all circumstances. You never know when you’ll need to use it again!
