Could this be construed as unfair dismissal?
OP was prevented (whether through company incompetence or intentionally is still unknown) of completing a nationally accredited course funded by work so he fails. He understandably is a bit miffed at this and the company and has really no choice but to seek employment elsewhere which is more equitable to his skills/experience portfolio.
He doesn't have a choice because the course was a waste of time and he is locked into his job (which we have heard he is doing all sorts of things for much lesser wages) because they will charge him the full fee if he leaves the company.
Rather underhand practices imo. Surprised so many people on here agree with it...or maybe i shouldnt be surprised
