I still don't understand where Phil gets the idea that his partnership removal was considered a breach of contract. I don't believe he is fully talking out of his ass since he usually makes sure his lies have a bit of credibility or are technical truths ("we didn't just get Jasper, we've had him for months").
9. Term and Termination. The term of this Agreement will begin upon our acceptance of your Program application and will end when terminated by either you or us. Either you or we may terminate this Agreement at any time, with or without cause, by giving the other party written notice of termination.
Granted, this little snippet is from the Affiliate agreement, but I'm positive the same clause exists in the Partnership agreement as well. Twitch reimbursement is essentially at-will contract work in agreement between both parties. According to this little piece, when removing Phil from the Partnership program, they did nothing wrong and everything correct.
Even if the termination was a breach and Phil believes they wer in violation of his worker's rights, WA is an at-will state so it wouldn't matter. Beyond that, as stated, Twitch streaming is technically contract work.
