I don't get this whole thing. Whatever happened to talking to your superiors about this kinda stuff? I've taken plenty of "sick" (of this job) days over the years and often times would proactively tell people to stay home if they were killing themselves (even locking out their accounts, if they went home and tried to work).

This had nothing to do with "mental health" it was just part of keeping people happy and not letting their work dictate their lives.
