I'm sure the answer is no, because most would agree that where possible, people should be able to arrange their working hours in a way that best suits their needs and mental/physical health.
With respect, I don't believe this.
In some roles, eg self-employment, this may be possible. (But even then, client needs may dictate otherwise).
I work for an organisation with a strong degree of flexibility in terms of options to work a shorter year, career breaks, various forms of leave & part-time / job share opportunities.
However, this is also balanced against the organisational needs - for example a p/t staff member cannot always choose the days or work pattern, as it is subject to operational needs.
Similarly with WFH, it's provided on a business need - in my team, colleagues could express their preference for wfh days & I agreed to this where possible, taking into account numbers of staff needed on-site etc. if we have a need for staff to be on-site on a WFH day, they understand they are required to attend.
Where possible I & my organisation will provide every support to someone with a problem or family issue - but they can't unilaterally decide what suits them best because it has to meet the organisational need.
