This is a point of law I have had a run in with myself not to long ago, with a company in Portland Oregon. For me, the final result was - I walked off, left my hard work behind and went to new pastures - because I lacked the cash/desire to fight it, and had done a similar "my really bad". Since then, I have found that most employers know they have you at a disadvantage and will press the issue of allowing them this feudal "right" of choice over your creations - or deny you employment. I think that some legislature to prevent such bullying is needed, and have written my congress-people concerning this. However, I think it will take a mass outcry before anyone really takes it seriously. Till then - read carefully, push back as much as you can on the issue and find a balance of earning a living and keeping your freedom of creation. Perhaps, write your own congress people with your fears and add to the urgency for them to listen
Tilly - I really feel for you man. This sucks bad - and it sounds like
you are even more entrenched than I was and cannot extricate yourself with out
extreme cost. This frustration must hurt terribly - I wish there
was something we could do for you.
