There’s no such thing as Ghosts but there are such things as Zombies. I should know, I was one. They hired me for a period of about 6 months part time as part of the bridge to employment scheme from the job centre. I had to fill in all kinds of forms so that they could make sure I wasn’t some kind of weirdo. Then there was the police background check which took around 2 weeks. Pretty extensive. So next time you go criticising Zombies just remember that they are highly skilled individuals on their way back to the work force.
