We're only hearing one side.
She said "Disney" told her to take as much time as she needed. Who, exactly, is "Disney?" Did whoever said this really have the authority to do so, or was it her direct supervisor, who might not have had permission?
So that's the first question.
Then, what is their usual policy? I'm sure she is not the first to lose a spouse, so there must be some precedent. Just as not all people are ready to go back to work following surgery, not all people recover from grief in the same amount of time. But there has to be some standard, or they could have people still recovering a year later, or be like my grandmother, who still broke down when thinking of my grandfather decades after his death.
I know when my husband was moving to another country to do a fellowship, I applied for a 6 month leave of absence, which was the maximum amount of time that they would keep your position open. (Unless you were drafted or called up for military service) I know that many employees applied for this after the death of a spouse or child, then shortened it if they felt better sooner.
Does WDW have a similar policy? :shrug: It doesn't appear so, but I don't know.
I also don't know her cultural background. Some cultures expect you to keep everything inside, and feel that you should suck it up and just get back to "normal" ASAP, while others would be horrified if you weren't expressing outward expressions of grief for weeks or months afterward. I myself went on with a big celebration a week after my mother's death, and knew someone who held their wedding as planned two weeks after their father's unexpected death. (he was younger than I at the time)
