I accepted a new offer of work, and then while on-boarding, they asked me for my Facebook link. I declined to supply it, because I have political, religious, and offensive humor on there... that would be completely inappropriate to share with a work group.
They are demanding a link though, because the group uses Facebook for their ongoing communication, coordination, and other development (i.e. scrum). I realize I could create a new page, but that still ties to my personal account that I can't share professionally.
I know I could use a separate email and create a new FB account, but that violates ToS, and can be problematic for other reasons as noted in this related question: How to separate personal Facebook from professional FB while getting full benefit of FB? Another answer to the linked question is to manage it very hands-on, who is who in which group, and what posts go where... but that sounds like regrettable mistakes just begging to happen.
Any ideas on how I can better isolate / partition the personal and the work Facebook activities?
