Here are some great tips from Miriam Salpeter at the Newark Examiner to "help the busy employee who leads a double life as a job seeker":
Do NOT - I repeat - DO NOT conduct your job search while AT work.
Spend some of your “down” time prepping for a job hunt.
Invest in yourself [and having] materials [that] represent the best you have to offer.
Network! Open your eyes - networking opportunities are all around.
Keep connected and engaged in your current job, no matter how difficult it is.
Gather information...about [prospective employer's] timing.
Above all, recognize that the positive steps you take now to manage your own career will pay off in the long run. Don’t wait. Don’t let stress or fear get the best of you. Take the wheel and turn the key.
