This or simply more vacation( I would prefer more vacation but it's probably harder to implement).
My controversial opinion is that half of the work is unnecessary (there's surplus of labor that has many negative consequenes for society at large - in short a lot of effort is pointless/missdirected as competition due to surplus locks many people in slavery(serving others more than themselves)).
It could be easily solved by people working simply half of a year. Lack of monopoly(all year round) on certain roles would benefit most enterprises and people would have time for exploration/education.
My hope is that external pressure such as rising asia will give some room for such progresive ideas in the west. They might even end up more competitive in a world that rewards creativity(derivarive of leisure) and education.
