Since I left that place and I believe most of my time-limited terms have expired, IP is one of the very few things I'll get caught up on with a contract. I'm flexible around hours, reporting, attire, presence, etc, but IP outside of specifically client-related work activities is where I draw the line.
I am a digital creator on my own time, I always have been since I was a child, I draw inspiration from many sources, whether it's work or books or videos or art, or even just a random thought. The notion that one day one of these things randomly becomes successful and a bevy of previous clients lays claim to the fruits of my labour sickens me to the core and goes against every sense of living in a fair and just society.
I've knocked back clients who refuse to budge on this issue. I'm no Bill Gates or whatever, but there's absolutely no way I'm signing over rights to things I invent or innovate on my own time. If the people I work for want access to that additional service beyond whatever monkey-shit I'm doing for them then they can pay for it and not just swipe it through some boilerplate IP clauses.
