And I have worked for creative directors who have gone to great lengths to make sure my partner and I were receiving the credit.
One of the most motivating things a creative director ever told me was, "I used to be nervous we'd hire people who wouldn't win awards. Now I get nervous we won't hire people who will go off and start their own award-winning shops."
A creative director who's willing to help your career is a valuable asset. Make sure you find them. Once you do, make sure you deserve the attention they're willing to give.
