Yes, you should be getting paid. Best if the client pays you directly.
My last gig, nothing left the station without a fee. We, for the most part, set our own rates.
You don't mention what market you're in, so there's no throwing out a dollar amount here. If this is a long time station client and this has been their deal for a while, it may be hard for you to do anything about it at this time. What you can do, is lay the groundwork for future business.
At my last gig, we created a "Production Handbook" In it we laid out all of the things a sales person needed to do to get their spots/promos on the air including; deadlines, turnaround times, copy length, tips and talent/producer fees. Every new salesperson received a copy and we would meet with them to explain how everything worked. Management was on board and appreciated having everything laid out simply and clearly. There was never any question what the policy was and no one could claim they "didn't know." There was also very little quibbling over fees.
The thing to stress to your management is, if you control the creative, you control the buy. It is good for your station to be viewed as the one who's production is so good, they charge for it, and at a bargain compared to what an agency would charge.
Good luck.
