There are two issues
1) intellectual property rights (IP) Unless she signed something to the contrary, I believe in the US they own any that she created during her time there. ( Canada is the opposite, the worker owns it unless something to the contrary was signed, but I’m not a lawyer)
If she was ever to publish, she may want to seek legal advice related to her IP. It on the other hand she sights it as anecdotal evidence in something she publishes that may be ok but again seek advice
2)should she be a nice guy?
Why
I charge for my value not for my time
I’d like to be nice by I can’t be. My shareholders would have my head for giving away my value
I’d propose a program for them and implement it based on a valuation based on monetary savings or lost days or whatever
It would be a hefty sum, take it or leave it
Hire someone else to implement if she has a strained relationship that would make working there difficult
License any new IP to them, don’t give it away
Partner with me if she wants, ( I’m already giving away too much value here for free now )
