I understand that my material was hosted on servers which my district had access to, that was my downfall and lesson learned for sure! I've known many people who host material on their personal gmail and now I know why. I have no problem sharing but I would like credit for my work and to give my consent. I denied my material because our communication was through email and it is a delicate topic, I would've preferred to meet face to face and talk about Sharing material and project/labs I've done. That is collaboration. I don't like that I discovered my material automatically shared with him and no one notified me, no one asked. I made myself available to him and he decided not to contact me or see me once he had access to it. Im not saying it's his fault, he doesn't know I created it, for all he knows I probably inherited it. I would've preferred a notification through email or in person.
