Hello Michael. I'm wondering how things turned out for your wife and her job change after maternity leave last year. I've found myself in exactly the same predicament. I'd be most grateful to hear any advice you can offer. I'm meeting soon with Citizens Advice and hope they can shed light on my rights. Work is trying to make out that my new role is of an equal status to my role prior to maternity leave, but it's far from that! Best wishes.
