Can ask the exact same question about many employment things at that end of the jobs market.
Everyone is treated as disposable dirt because they assume everyone will take anything, even for free and work their arses off for nothing in the hope of eventually getting paid.
Saddest thing of all, the Job centre pushes places like that to get folk off their stats.
They still get JSA whilst "on trial". if they refuse to take the trial, they're deemed rejecting a job opportunity and sanctioned.
Just to further my above post. the whole Job Centre/JSA process is a lot more sinister than folk really realise, they're happy to take government statistics at face value.
Having been in that systems and working alongside volunteers in it at the time and hearing their experiences, it's no wonder the suicide and starvation rates are so high.
Example above being one- sent to work a full weeks labour for your pittance of JSA in the hope you'll be kept on- gets you off their casebook for a while if nothing else. Employer gets a desperate worker for free, paid for by government. Reject it? Instant sanction. So you can't.
"Educational centres".... these are a fucking cracker.... Sent on to be "educated" somewhere else, educated in what? Fuck all. There are no lessons, qualifications or certificates, It involves being interviewed every day then sitting in a room for 4+ hours whilst somebody walks around the room supervising you to make sure you are job searching. Of course it's packaged as "support", it's not.
The people at these outsourced, privately run centres are incentivised to get people sanctioned (allegedly £80 if they hit their quota). Their favourite trick is to schedule an interview with you by letter, only for you to show up and find the person conducting the interview is not there and be told "We're very sorry, that's our fault, we will reschedule it, your advisor will send you a letter confirming the date and time, you can go".... 3 days later, they get a letter with their new appointment....2 days ago (they'd rescheduled it for the very next morning, no phone call), Person goes in or phones and is told they have not attended a meeting, have breeched the terms of their JS agreement and have been reported. Job centre immediately sanction. Letter submitted as evidence? It's dated the 19th, your interview was the 20th, you got it on the 22nd? tough titties, in their opinion, you should have been phoning them every day. Sanction stands.
I've had to deal with volunteers coming in, in tears terrified they can't pay rent, for food etc because they've been shafted like that, thankfully knew enough about it and where to point them locally for the best advice on where to access hardship payments and the like.
Don't get me wrong, there's a good number of folk who likely deserve some of the sanctions, taking the piss, trying to milk money for nothing, but the vast majority are not, they're just stuck in the system that should help them, but can't get out of it because their safety net is doing more to hurt them.
I've even seen people sanctioned for not attending reviews when the reason they couldn't go was having a job interview the Job centre sent them to!! Attend interview = Not attend Job Centre when requested (they'll refuse to reschedule for anything) = Sanction. Not attend interview = rejecting a job opportunity = sanction. Rock, meet hard place.
