Relatedly, I just left an upscale Yoga Retreat in Goa (Purple Valley) and the staff and managers had been there for years.
If you're a yoga person and get that gig, you only leave to go to another such place, where again, openings rarely occur. The Indian staff were also lifers.
Every two weeks, it's a different group and top teacher. Your life is yoga and waiting for Friday: Vegan Mexican Night at the buffet.
Purple Valley also has a branch in Tenerife and in the Goa off-season, they migrate there.
Mostly brits, a few South Americans. You need multiple languages.
Similarly, an eco-resort has a different set of strict requirements and the same low turnover. A lot of smart and dedicated people want to live in the jungle and are happy to take low wages. I stayed in one in S. Laos. A few whities there were working there just for meals. There'd be a line out the door to replace them if they leave.
