To be devils advocate - do you expect your employer send flowers and give vacation days when your parents pass away? Or advance your salary if you short? Or tons of other forms of flexibility in return?

In societies where all of this is encoded in law they seem to be doing worse off than where these things are based on trust.

Australia's doing fine and we have bereavement days. Somehow our employers find the capacity to still provide flexibility. No, it would be unreasonable to expect those things from your employer and yes it's better to have employee protections actioned within the law.
