Not only did she take money for hours she wasn't working, but when she was asked about it by a GP partner, she doubled down and denied having done it. It was only when she was taken to tribunal that she admitted her wrongdoing, presumably because the evidence was clear.
Aside from any harm that could have been potentially caused to patients, and defrauding the practice, health professionals have to adhere to a code of conduct which holds them to a high standard, so that their behaviour does not bring their profession into disrepute. Lying and fraud is disreputable behaviour.
I'm another one who thinks she's got off lightly.
