Haha, no. The role of the Job Centre is not to get you employment, but to fudge the unemployment statistics as much as possible.
They don't care if you get a job or not. But they do want to get you off JSE as quickly as possible.
If you are good at gaming the system you can claim for years with no prospects of getting a job at all; if you're actually trying to get a job the Job Centre is the least helpful place in the world.
Your conspiracy theories and JC's effectiveness in finding claimants employment aside that is their official stance on the matter, and yes generally if you are off the dole then you have generally found employment, no? Regardless if they had any role in facilitating that.
