In this turbulent marketplace, it\u2019s no surprise that many people are scouting for new opportunities before their job hits the chopping block. If you\u2019re one of them, here are some tactics to make sure you don\u2019t jeopardize your current job in the process. Because your staff may be thinking along the same lines, you might also want to leave this article where they\u2019ll find it.Respect your current employer. Avoid using huge chunks of your workday for your search. It\u2019s unfair to your current employer, and "[your prospective employer is] going to think less of you for dissing your current employer," says Laurel Touby, founder and CEO of Mediabistro.com, a media industry job-search website. Touby also warns against using company supplies, or searching the Internet at the office. Be selective about the interviews you schedule. Don\u2019t rush off too quickly to interviews. You may find you\u2019ve wasted your time. An initial phone conversation off-hours is a sensible first step. Plan on being discovered. "Accept the fact that your employer may find out," says John A. Challenger, CEO of Challenger, Gray & Christmas, a Chicago-based outplacement company. Rehearse what you\u2019ll say if your employer asks you about your job-search. Allow time for the search. "You have to commit to this process as if it were a second job," says Touby. Give yourself plenty of time to find the right position and expect it to take at least three to six months. "Don\u2019t do it out of desperation. Do it before you need to."Network like crazy. "Social, professional and charity groups are filled with working people. Talk to everyone," says Challenger. Touby suggests you establish "weak ties," friends or associates of your own friends or associates. Distant connections can seem more credible as references for a job, she says.Whatever else you do, Touby says, "don\u2019t emphasize your weaknesses or the company\u2019s problems," she advises. When the inevitable question comes about what went wrong on past jobs, remember, the real question is, What did you learn from the experience?
