I have been with the company since late 2021. My original contract is an indefinite-term (permanent) agreement with no expiry date for as-needed work. While there are no guaranteed hours and the role includes extended periods without work or pay, my active working hours typically average 37.5 hours or more per week, occasionally exceeding 160 hours within a two-week period.

Management has recently presented a new contract that introduces significant material changes to my terms of employment, including a restrictive intellectual property clause requiring the forfeiture of my IP rights, and a provision stating the contract will automatically terminate if I am not assigned hours for a one-year period. I have requested modifications to these terms, but management has indicated they are unwilling to amend the document. What do i do if i can't give away my IP rights? and or am unwilling to agree to the new terms?
