For every O'Donnell there are a fuckton of ordinary, low waged employees who have been unfairly dismissed because they are pregnant / wrong race / have a disability / pursued a sexual harassment complaint / they're a whistleblower, or they've been bullied and harassed because of a personal vendetta, or have faced unfair redundancy or have been denied sick pay, holiday pay, maternity pay, just their normal pay ... or they've been denied adequate breaks, protective equipment, adequate training to do their job safely, or their employer has them in some sort of bogus self employed contract or just hasn't paid their NI ... or many other disgraceful things.
And if ordinary low waged employees cannot afford to bring any of these bread and butter cases to tribunal because they risk having to pay their employer's legal costs if they lose then we can all wave goodbye to our most basic employment rights because they are unenforceable.
Let's not throw the baby out with the bathwater.
The ET appear to be quite good at 'sifting' cases from what I have seen - I don't think many truly vexatious cases get through. It would be interesting to look at the thresholds and compare them with BCHRT.
