Let's say you get this offer with a yearly salary of $104,350. With 2087 hours as the full-time expectation that would be $50 an hour.

However since they want to own all of your creations that might happen while not at work I wonder if they would accept a counter offer. Would you accept this counter offer?

At $50 an hour, 8760 hours in the year, my expected full-time salary would be $438,000. Before you suggest I cut out sleep time what if the idea or solution comes to me in a dream?

I think that is a good compromise. I have the expectation of being "in office" 2087 hours out of the year while also collecting on all of the chance ideas that happen the rest of the time.

Edit: I like this idea. A clause. I collect $104,350 a year. But if Amazon claims ownership over a personal project I create then the rest of the hours uncollected over my employment are owed retroactively. So I work there for 5 years before I have a successful personal project that Amazon wants. They then owe me $1,668,250. Pennies to them but a good chunk of change to me.
