Find Your Own Replacement

If you want to get promoted into another job or another shift, make it easy for your boss to promote you. Remember from school- how an object at rest stays at rest? That is your boss. He or she is perfectly happy to let you stay in your current position forever. Why? Because to move you means he or she will have to replace you and since you are brilliant, that will be a real pain. So make it easy for your boss and help them find your replacement.

If you have writers, groom them to transition into your job. Give them more responsibilty. Have them produce a whole segment (with your supervision). Let them booth a block of your show. This system is a two-fer. It grooms your replacement but also shows your boss you can be a manager.

If you don't have anyone in house, let your fingers do the walking. Start flipping through your rolodex for buds from college or friends you have from other stations or markets. Ask them if they are interested in a producing gig or if they know anyone who is.
Have the interest parties call you and you can walk in their resume to your boss. This is also a two-fer. Once you start making calls like these, you will have people start returning the favor, alerting you to jobs well before they are ever posted.
