First question: what is the agreement between coworkers and the organization? Is their something explicite like a work contract or something?
There are contracts, of course, but the working hours are not specified in it.
Then, second question: what role is dealing with partner issues and this type of contracts? Do you have a role for that? If answer is no, then you must define it in governance.
Currently we have no role for that. Could you please explain, what would this role be accountable for?
