A “good work” strike is a form of labour organizing where employees provide service at the employers expense, rather than walking out. An example would be Lisbon bus drivers in 1968 who continued to run their usual routes whilst on strike but did not charge for ridership. A traditional strike involves withholding your labour completely. 

The nordic model of sex work decriminalizes the selling of sex acts, but criminalizes the purchase of sex acts. It also criminalizes any means of profiting off of the sex work of others, by charging to facilitate sex work (eg. pimping, advertising for sex workers, renting to sex workers)

Some sports separate athletes into distinct leagues on the basis of relevant anthropometric classifications, which are biological distinctions between athletes. An example would be weight classes in boxing. Sports that are not traditionally divided in this way still have distinct body types that create different styles of play, such as height differences in basketball.

School vouchers are credits, (equivalent in value to what a government would typically spend on public education per student), provided to parents by the government to subsidize tuition at any school of their choice; whether it is a governmentally overseen public school, a private school, a charter school or a homeschooling institution.
