Exactly the same thing happened to me!
When I was 17, I managed to get a pretty decent technicians job for a small re-sellers firm
The set up was weird aside from the Scientology part - I wasn't allowed to leave this familys house for lunch, and I had to eat lunch with them at the table (i thought this OK coz I was allowed to smoke as much as I wanted..)
I went through a rough patch with my EX at the time, and was off ill with a tummy bug for a day...I came back and instead of sympathy - I received stern words along the lines of "You've let us down, only weak, wrong-doing people get down and ill"
They then asked if I'd like to take a read through some self help books, i thought "yeah why not" I was feeling low at the time and was open to any suggestions to pick myself up
I asked if I could take said books home to have a look through as I was busy at work - they said no. They said I had to be with other Scientologists whilst reading them, and that this had to be done at their house....
I said..hold on, I'm sorry I'm not religious in anyway, I'm not up for that...
The next day I had a letter entitled "Termination of Employment" under grounds that I was "underperforming"
I never signed a contract with them so I couldn't take it further with industrial relations.
My IT career was ruined and I had to work in a shop earning minimum wage for the next year. Thankfully I got myself back up and I'm running and IT department now ;)
These people are poison in our communities - they prey on the weak and persecute those who don't "buy in"
