Many people teach English online part time while devoting their full time attention to a creative endeavor, such as writing a novel or designing an invention. If this is you, then don't sign a contract with Cambly! Section #7 refers to "developments," and agreement with this item compels you to give Cambly your "rights, title, and interest" in "all inventions creations, improvements, discoveries, methods, developments, software, and works of authorship, whether patentable or not, that are created, made, conceived, or reduced to practice by him or under his direction or jointly with others during the Service Period, whether or not during normal working hours or on the premises of the Company." It goes on to say that if you refuse to sign a document that they want you to sign, "Tutor hereby irrevocably designates and appoints each executive officer of the Company as his agent and attorney-in-fact to execute any such papers on his behalf to take any and all actions as the Company may deem necessary or desirable in order to protect its rights and interests." So by signing the contract, you give them the proxy power to sign any document using your signature, forcing your legal compliance. I've taught ESL abroad for 6 years but this contract is on another level. It's normal for your employer to own the rights to things that you create at work. It's another thing for them to own EVERYTHING you create in your free time, too. Cambly could legally pursue any royalties you may earn from any creative projects that you complete while under contract with them.
