Gosh I don't envy your situation. All I can tell you is send them on a trip for the day, say to the mountains or somethiing, and make them pack a lunch. (do they have a car or do they use yours?) and while they are gone, take all thier stuff and either put it on the lawn or put it in storage. Have some of your friends help out with this. Change the locks. When they get back, sit them down and tell them they no longer live there and that they will have to find some place to stay for the night, and they had better find a job or they won't be eating either. Recommend temporary work places, like labor ready (they hire you on the spot if they have room and pay you right there too, they can also work nite shifts and weekends) have them do that until they can get a steady job. a good place to look for jobs are at workfirst at the DSHS office, they also provide resume' building, how to get a job, interviews as well as open positions throughout the county. I would say after a couple of weeks of being forced to be grown up they will either learn to sink or swim. If they are still having trouble finding a job after six months, then go back and help them, but it will be easier for you to put down ground rules, and have them sign a contract saying they will be there for x amount of time, and will put out applications and resume's everyday, (x amount a week) and will pay for room and board. hopefully you'll see a marked improvement :)
