I'd be happy to see full time employment re-defined as 20h/week. On a good day there's 4 productive hours in me. Cut my salary in half but release some of my time so I can live a little. .

Upside would be - 20h a week to invest into family, hobby & entertainment. - "more jobs" are created ... - limit supply of labour solving unemployment (no need for UBI anymore?) - Salaries would creep back up somewhat due to higher productivity per hour
