If I were an AAPL shareholder, I'd be very pleased about it. The behavior indicated in the post very much leaves the company at risk of spending possibly hundreds of thousands of dollars on legal counsel and settlement fees/court-ordered payouts.
Getting away with only an apology and some time off is a bargain.
As for your last paragraph, perhaps there's a distinction between necessary stress and unnecessary stress. You seem to be describing necessary stress -- the stress that's intrinsic to working at a company, facing deadlines, negotiating with clients/other departments, etc.
By contrast, this woman describes a pattern of being on the receiving end of personal attacks based on items unrelated to quality/delivery of work. That would be a very different sort of stress from what you're describing.
