So, my brother worked hours week after week which weren't on his contract. He confirmed it with his manager, and it became his habit to just do it. Every week, the managers signed it off, essentially saying "everything fine here." We work in the same shop, so that's how I know about the procedure and so on. Anyway, suddenly it became an issue. Their first step? To skip the "let's talk" stage - the "hey, we noticed this, come here and we'll tell you you were wrong, don't do it again" - and went straight to disciplinary. He went, but they'd forgotten to arrange his union rep, so they rescheduled.
Come the actual disciplinary, my mum wrote him out a statement which he could read. He read it, and may I say it was both hilariously accurate and called on the managers to jump through some hoops and then reconvene. Only, the member of senior management there didn't like the sound of that, so threatened him with fraud instead. The union man was worse than useless, and my brother caved (alas, he caves under pressure). The member of senior management, upon drawing a confession that my little brother was in the wrong, stated - and here I quote from the transcript of the meeting - "what's your mum going to say when you tell her you're a liar. She wrote you that statement and it's lies."
Right bastard. Anyway, my brother has been harassed enough by management at this point so moves to another shop. He was working from five each morning, happy to do so, liked the work. The happy being that now they've no one to do that shift, so the managers responsible have to get up earlier and go in.
It gives me a certain sense of grim pleasure.
