Universal Basic Income: sounds like lazy thinking but really, you want people to work and be productive and get shit done, give them enough money that they can go "hmm, nice and relaxed, took time to care for my needs. Now I'm kinda bored, I know I'll go see what jobs are available, I get get myself treats with the extra cash and help the economy and help my community".
Real access to support - more funding to mental health services and social care services and charities that support families. Free breakfast clubs and after school clubs. Childcare support and/or legal protections in work for parents who need to be more flexible around school holidays. And free education for life, that means primary through to university through to additional learning or career changing in adulthood. The workplace would be far more productive this way and fewer barriers to entry.
Oh and seriously, ban 0-hour contracts, if you can't afford to properly employ workers with the proper legal protections and duties then don't have workers, it's not that hard. End exploitation.
