You can do everything right, and things can still go splat in your career. As John Elway, two-time Super Bowl champion quarterback, says, “Not only do you have to be good, but you have to be lucky.” Keep alert for some of the warning signs your job is at risk. This is not to be defensive but offensive in managing your career. * You sense disregard for your authority by those above, below, and around you. * The number of people who report to you is significantly reduced; budgets are cut. * You increasingly feel that your energy, enthusiasm, and smarts are getting you nowhere. * You experience notable indignities, such as being ignored in meetings, being left out of the loop on key decisions, or being omitted from the circulation lists for important e-mails. * You have frequent run-ins with peers. * You are repeatedly passed over for the most interesting, important, or prestigious assignments. It's smart to pay attention to your gut feeling on this. Before you get panicky, ask questions to ferret out feelings vs. reality. Regardless of what you hear today, prepare for being “unlucky” someday. Keep your resume updated, and step up your efforts in expanding your network of contacts. Prepare emotionally and financially, so you regain a sense of control in your destiny.
