Looking at it from a labor law perspective we can look at what other countries have done. Sweden for example do not provide any paid grieving period, but labor laws does give a right to take a leave of absence. Unions often extend this to paid leave, but also limits it to a set number of days, and often the amount seems to be a single day for the funeral.
What I have seen for actually grieving is that either people go back to work or they go to a doctor and get diagnosed with acute stress or depression because of the situation. I suspect that if the case in the article had occurred in Sweden then that is what actually would happen and the person would have got a few months to recover.
