It would be revolutionary! I find myself overwhelmed balancing life responsibilities, work responsibilities, investing in relationships, and finding time for rest. Having an additional free day would create more opportunities for my non-career investments and truly transform my life.
Allow me to use weekends to travel, explore and try new hobbies. It will help me during the work week to stay focused and stay on top on items to be free for the weekend.
Make me more productive. As someone with ADHD and neurodivergence it would make me better able to focus without getting burnt out to ensure what I make is good quality.
It would allow me to focus more intently on work projects and actually have time to recharge properly for the next work week. Studies have proven this already but as a country, we are behind.
Have two weekdays off to actually take care of medical appointments. Honestly, this is also why healthcare can't be a 9-5 either. We can't keep having everything happening at the same time.
Having either a Monday or Friday off would allow me to get some greater enjoyment out of a longer weekend, but would also make it somewhat easier to schedule medical appointments, etc because I'd have a "weekday" during which I could take care of those things.
Having an extra day off can allow for more time to engage in physical activities, relaxation, and self-care, which can positively impact my physical and mental health.
This would be a game changer. A four day work week would allow my 'off time' to actually be restful and relaxing, instead of my current state which includes cramming in every errand and appointment!
