Hello:
I am a social worker, and have a bachelor's in social work, so I am not sure if that is the same thing as the social service worker program. It is mostly paperwork, and lot's of it. There are multiple and varying deadlines that have to be complied with, and lots of crises with consumers that need solved. So a very stressful job, if you can manage your stress it may work for you. I have BPII so I struggle sometimes with the unrelenting demands of my job, as do all my coworkers. It's pretty tough. I make $30,000 per year US with health insurance and about 5 weeks off a year for vacation and sick.
For a child and youth worker I am not sure if that will prepare you for youth case management, the pay is about the same as my job. If you go work in a group home(I have done that also) with children or young adults the pay is about $20,000 per year in my area. More contact with your consumers, less paperwork, more fun.
Hope this helps! Good luck in your choice, you can pm me if you need more info.
