I've just had a read and it doesn't say a lot unfortunately. On the face of it it does sound like it could be unfair.
What I'm not clear on at all is whether she still works there. It seems like she does.
I've never seen someone take a case against a current employer, so I'm a little confused. I'm assuming it can't be an employment tribunal because she'd either be going for unfair dismissal (they got rid of her owing to discrimination) or constructive dismissal (she left owing to discrimination). Instead this sounds like she is still there but is taking them to court. Does anyone know if this is normal? I would have thought it's more usual to raise a grievance within work and follow the internal processes (which may still end up with unfair or constructive dismissal if it can't be resolved).
I'm happy to be corrected if I've got the wrong end of any stick.
