I don't think "work hours" is really an applicable concept for someone in Carmack's position - he's not a 9-to-5 worker, his life and work are surely much more entangled.

It's hard to deny that Carmack's involvement in VR was linked to his position at id (Zenimax by extension) in a way that Armadillo for example was not; if nothing else, he did talk (show?) Rift versions of id properties. However, his image, popularity, visibility and even open promotion of Oculus are not really at issue here, at most they would have been grounds for disciplinary action from Zenimax at the time.

It's up to Zenimax to prove exactly what sort of tangible, protected IP and 'know-how' was transferred to Oculus. During 2012 he tweeted often about his research on lag, and I imagine his work was more extensive than what he publicly disclosed. If there's any link between that work and any properties of Zenimax, say a computer, email address, code or assets owned by Zenimax and used in any way to do VR-related work that Oculus took advantage of (even if it's not in use today), then there will be blood, pain and tears.

Carmack also tweeted and spoke often about Zenimax refusal to touch VR and support Occulus. He basically said Doom 3 BFG Edition VR support was done by him OFF the clock and he would have to buy HIMSELF from his own money all the copies that went with Occulus KS fulfilment.

Basically Zenimax didnt want to do anything with VR while he was there, but now those slimy lawyer cockroaches want piece of the action.
