Ethical Guidelines for Work Trader/Live-in Volunteers in Communities

I hope this is the correct forum in which to make this posting!!
Are there articles/books to read...people to talk to...etc...about how to develop an ethical work trader/live-in volunteer opportunity for our farmstead ...and how to identify an ethically based work trader “host” opportunity??
I read so many different interpretations of what is acceptable by hosts on HELPx, Workaway, WWOOF, etc...
Questions like—how many hours/day is an acceptable requirement for various combinations such as the host provides doesn’t provide:
lodging and all food/amenities;  lodging and no food; all food but no lodging; a stipend (how much/week?) for food with either lodging or no lodging; the volunteer provides their own lodging and food—the host only provides utilities hookups, possibly access to kitchen, bathhouse...etc!!
The host providing a toilet is a given!!...but what about a shower facility, free WIFI/utilities and laundry/kitchen use??
I have first hand experience in work trader situations like all of the above!!  Having to pay to use WIFI...laundry...providing most of my food...etc...and still being asked to work 5-6 hrs/day for the “host” enterprise!!
Of course...I and all other volunteers can CHOOSE for which host we want to temporarily hitch our wagons to!!...I want to educate myself as a work trader to identify opportunities where I’d risk being TAKEN ADVANTAGE OF!!...and also learn how to be an ethical “host” to work traders myself!!
I’ve never yet been a “host”...so perhaps just investigating the work trader “host” sites for guidelines is the answer??
ADVICE??

I added your topic to the woof hosts and volunteers forum as these seem to apply more to your topic.

I looked through our book section and found a couple of books that might be of interest.

He lays out a step by step process of why this is important, how to mentor young folks, the nuts and bolts of selecting, paying and housing young people on your farm and he gives advise to young people who may be interested in becoming a farmer but may not know where to start.

While this book provides a wide spectrum of practical information on the physical systems designed into a community-scale homestead, Trought also reviews the economics and organizational particulars that D Acres has experimented with over the years

Also, you might try looking at some of the woofer websites as I believe they offer some guidelines.
I hope you will find the information your are looking for.

Thank you very much for the information!!
