My job is considered to be volunteer work - would get certificate for "thank you for volunteering blah blah" from the City.
I work for the after school program , a non-profit organization (STS Academy) for students to go to after school. It offers tutoring, recreational activities, a lot of competitive contest amongst schools. I've taught for 4 years now from grades 1-4th. What got me started was that I needed a job and it paid well and hired any college student, basically.
I use to love it but... seriously, kids have dealings with the devil. Haha. I've grown tired of it and dealing with 25+ students on my own and complaints from parents and bosses - it does any body in. Seriously, I laugh when parents say their kids are "good little angels". Hookay. Regardless, I love my kids and treat them as if they were mine and I learned loads in this job.
