If it had happened in the US, I would suspect that he was sent back to jail for getting a job intended for an illegal alien.

Legality is the bane of the just.

This is what happens when rules aren't principles and when you teach obedience instead of thought.

Summary:
48 yo man is released from an open prison under parole. (August)
He had to be supervised and wear a tag, and was subject to a night-time curfew.
He looked for work, was given a trial as a driver, then given the job. (September) He bought his own uniform. He had to start at 6:15am but the rules said curfew till 7am - the supervising parole officer said this was ok.
At his next parole interview he was put back in jail for curfew breach.

Comment:
At least in this case the wheels of government may still be turning, by rights he should, eventually, get the ok for the job and an apology, a commendation even, to expect a rethink by the admin people is likely to be a bit much.

Typical government thinking- expecting a man to step out of jail and go into cold storage while the bureaucrats ponder over a decision.
They assume he would be just another long term welfare client, instead he took commendable initiative by finding work.
Rules, procedures, forms, signatures, approvals,schedules, licences, management, signing-off, ... no sense of time, no concept of the needs of the man needing work. This is what Einstein meant when he said 'Never forget your humanity'. An alien concept in the 'public service'.

Kind of silly really

Typical bureaucratic insanity in a world filled with drones that have single digit IQs and no imagination. "Go ahead and do it so we can send you back to jail and bilk taxpayers for more of their money" said the moronic prison warden as he started another video game. "Too busy for mere paperwork, have to get to the next level". What a load of crap...

Laws don't work unless they're just.

I hope he got something in writing from his parole officer. Official-looking pieces of paper are the one argument that (at least at times) makes an impression on people who operate by "policy".

No doubt Inspector Javert is in on this somewhere.

As Hipshot Percussion said (Conniption, Montana, 1881), "Just because it's the law, don't make it right."

This reminds me of when my Progressive auto insurance plug-in did not like driving to a night job.
Flo said, "No discount for dino!"
Like my now grown little girl used to say to her misbehaving brothers, "I'm tellin'! I'm tellin'!"

Don't think. Just follow the rules. Does Le Miserables come also to your mind?
Merry Christmas Gulchers.
