Looking past her editorializing, the Apple communications she leaked aren't really unreasonable. She raised concerns about harassment, so Apple started an investigation. She then complains that the investigation was "nonconsensual", despite being the one to raise the concerns. She then requested a second investigation, which Apple started. The part about being placed on administrative leave is particularly confusing, because this article says that she requested to be placed on the administrative leave.
Her Tweets are hyper-dramatic. She calls her Employee Relations contacts "Employee Retaliation" and even insinuates that she thinks Apple might assault her at her home after they requested a meeting:
> Any bets if I get a literal knock on my physical door from #Apple today?
> Hey #Apple, "This feels a little like witness intimidation. I let @NLRB know." Love, Ashley
> Clutches panic button & Mace while still laying on floor pondering the brutality of U.S. capitalism...
