Non-Disclosure Agreement?

[grimm]

So my company wants me to sign a non-disclosure agreement (i've been there for 10 years already) In anycase I do a lot of the photography for the company using my own equipment.

I do not want to sign the agreement because it would be giving the company rights to all of the photographs I took. Eliminating my ownership of the photos.

If i was using their equipment I could understand as it would be "Part of my job duties" but being that they don't supply me with equipment to do this, I see this as freelance type work.

just wondering if anyone else has been in this scenario and how it panned out.
