It seems I should be able to figure this out, but I can't. The facility where I had volunteered until last March is requiring me to attend a 2-hour meeting next week, in person, outdoors. The facility itself is closed to all except a few staff, including our boss.

We volunteers will not have access to bathrooms or running water. I'll be away from home for about 3 hours, not too bad.

Wouldn't there be public health laws that cover the availability of toilets and running water, or would those laws apply only to paid employees?

Is it unreasonable to expect a toilet and running water?
