My opinion on this is that employees turn up as a "whole" person at work. That means that what happens at home can have a negative impact on work and also what happens at work can impact on home life. Identifying the possibility of a risk with a worker and putting the required controls in place is a key part of managing OHS risk (fatigue, drug and alcohol etc. comes to mind).
While the part of providing leave to sort out issues is often seen as the controversial part, ensuring a person's safety at work and the safety of others at work is also important. When a person turns up with a sports injury organisations tend to assist with alternate duties or return to work programs but the opposite seems to be true for any mental harm. Most organisations accommodate the odd personal problems that crop up, from sick kids to getting treatment for a major illness. This is just one issue that is now mentioned specifically, and not every employee will take time for every issue they have.
