No. If you have a contract to get paid for work, it really doesn't matter whether you "own" the end product in any meaningful way. You should get paid according to the terms of the contract, even if it was just a verbal contract.

And taking credit for someone's work is not remotely the same as copying it without their permission, attribution intact. Can you not tell the difference?
