The new article in the Athletic makes it clear that the Celtics had no choice and a year year suspension is actually a light punishment. The consensual part of the relationship reportedly moved to non-consensual and then sexual harassment.
"Non-consensual" is pretty loaded.
I read it as, they dated, she called it off, and he continued to pursue the relationship, which made her uncomfortable. We of course don't know what type of comments he was making.
That sort of thing has happened billions of times, but in a workplace, it's hazardous. In terms of the Celtics as an organization, they're no doubt trying to shield themselves from liability, particularly after the Sarver punishment came down.
One question I have: if this was somebody in a lower position in the organization (i.e., a subordinate), why did the Celtics initially condone the relationship? I'm curious what team policy is regarding that stuff. And, if it's lateral or his partner was higher up than him, what type of comments would lead to a year suspension?
