True, and excellent point, but that does not change the fact that if you are receiving some form of compensation that is on par with the work being done than it is not volunteer work in the traditional sense. It is, as was said, much closer to a government job.
What do you think the value of sacrifice means? The value in sacrifice is in the helping of other people. That's why we talk about the value of sacrifice when describing military personnel but not when we talk about suicide.
That's actually really interesting, I've always interpreted the 'value' in that phrase to be a character trait. Whereas you are saying that it's 'value' as in an equation, so putting in hours volunteering = good outcomes.
No it isn't. It's to help people and/or the community.
