I've always been under the impression that workaways are 'unique snowflakes' who haven't come in terms with their mediocrity. People whose gap year have turned into a lifestyle.
I was host to many workawayers, usually travelling families on a world trip with their kids homeschooling while travelling. I was not looking for a slave but for people who can teach my kids or me something fun. Sofar we had: birdwatching, karate, fancy cakes, coding, of course lots of language practice, woodwork (building a pergola), stargazing with a proper telescope, juggling, painting a mural
We once had a guy for 6 weeks who basically played ping-pong every afternoon for hours with my son who within those weeks became really really good!
It was more of an exchange since I taught them about local history and German and we cooked together.
I myself did all my workaways in Croatia babysitting since I don't have anybody in Germany to speak Croatian to and I don't want to forget it but can't justify spending 6 weeks per year there just on vacation while my husband works so at least I don't spend any money.
