In many countries especially in the US an employer can be at fault in front of law if they allow or enable a workplace affair that results a divorce for example. As far as I can see, Big Brother is Tully's employer. They are also at fault if they know their work environment will worsen the worker's mental health for example. I've read of many cases where the employer has made a deal and paid six number figures in dollars to avoid negative publicity.
How are people even questioning this?
it's not a work place, you can't drink, pash, play games etc in your work place either. But yes they do sign a contract and i bet BB isn't liable for anything. Any way, they all have issues and so does everyone, what do you expect bb to do, pull her from the house because she cheated, or because she always cries, or because she owns drew? I'm sure if her family thought she was going nuts they would yank her from the house. She is fine when things are going her way, she behaves badly when they don't...she melts down then gets over it. What happens when she gets out is their business and none of ours.
