I think it might have more to do with two suicide attempts that took place while she was overseas, and it seems her employer didn’t know about that until after the third attempt succeeded.
Don’t you think that had they known, they might have made attempts to help her deal with her depression?
And if they knew, perhaps placing her in a position like answering the telephone was one day they were dealing with her mental problems, which, as she was surrounded by health professionals, might have been managements way of dealing with her condition...there’s too much we do not know.
Like who was treating her, what medication was she taking, was the hospital aware of what ailed her?
My guess is they didn’t know because she told them nothing.
The reason she told them nothing is because if she did tell them something, she would be regarded as a pariah, as some of the posters here have done, who would have lost her job and everything she did have to live for. :(
