The perception of your value as an employee is just as critical, if not more, to keeping your job as your actual value. You may be the best at what you do but it means nothing if no one knows about it or if you let your manager or other co-workers take credit for your hard work and accomplishments. The best way to maintain a perception of value is through simple self-promotion by always keeping yourself and your work in front of your manager and, to the extent possible without stepping on toes, the other members of senior management. In short, a bit of self-promotion may go along way to keeping your name off the lay-off list or placing you ahead of others for that big promotion.
