Not the first time bmi have left people high and dry shortly after offering them a job. There should be a law against it. At the very least there should be significant financial compensation which matches the severe problems caused.
Then they have the cheek to slap a bond on new recruits! All very one sided, isn't it! How about imposing a "bond" upon bmi as soon as they make a job offer which is accepted? That's called fair play (as if they'd know what that is!).
