I used to work at a call center ( one of my first jobs), were we worked long thankless days, taking verbal abuse from customers who called in, getting paid very little. I hated it. But the manager of the department kept telling us how good we had it, and other jobs are MUCH harder. Those words kept me at that company, until they dissbanded the entire department and then we were all out of jobs.
Now I look back and think that was the WORST job I ever had!
JW's are TOLD this is the best way of life - That everyone out in the world is miserable. They believe it. I might keep them in regardless of how unhappy or how many doubts they have. Its the fear of the unknown, or even the possibility of something "worse".
