Back at work, and maternity cover doesn't want me there

[NoWaterOnlyWine]

I guess I'm a bit later than most on here - I've actually been back at work for two months after maternity leave.

Long story short, my maternity cover is now a woman I job share with. She's angry she too had to go part time, and it's repeatedly excluding me, setting me up to look stupid, and bitching about me to colleagues. Spoken to management about the exclusion, her taking over all work and leaving me with the shit jobs ... the result was that I should have expected it by having a baby, going part time and needed to get on with it basically it's a proper campaign to get rid of me so she can go back to full time.

It's horrific. I dread going into work. I've been job hunting but there's nothing even full time within a 1.5 hour drive of here as of Monday, she's officially my 'boss' now, so I desperately want to get out of there.

I was wondering if anyone had any ideas? This is all really short term as I'm starting a degree in criminology and justice next year, and training as a probation officer after that, so I just need to get through the next three years. DH is currently deployed, so childcare is down to me and nursery where he is for three days a week. With nothing local, I guess I need to look at working from home. But I have no idea where to start.

Any advice? I'm on annual leave for a couple of weeks and the thought of returning is making me feel sick

Hopeful little bump ...

Sounds rubbish.

Why is she your boss now if you are job sharing? Who line manages you?

It's been decided that she now manages me by my manager, the one I complained to about her behaviour and unfair workload distribution. My managers manager sat in on the meeting and chimed in agreeing that the situation was my fault for going part time. It's been decided that I am 'inadequate' due to her endless attempts to basically make me look incompetent, either by making major issues of something minor, or deliberately changing something so I look like an idiot who doesn't know what they're doing.

So for example, I'm responsible for ordering certain items. I'm told one item we have been told not to order anymore by the audit team, so I don't.
She then makes a huge song and dance about how I haven't ordered this item, tells everyone in the office, until the point where my actual manager has a go at me. I've been off for a year! I assume that as someone I'm 'job sharing' with, she'd be updating me on things I'd missed, rather than deliberately lying about things

So she now is responsible for me and has been allocated an extra day in the office which she's thrilled about.

It is rubbish. It's so obvious she, and management, and to be fair probably most of my colleagues now want me out of there. A client has even raised with me privately how vile she is about me behind my back, and to be careful. I planned to keep myself to myself, but it's clearly not working.

But that's by the by I guess. My real question is about home working, if there's anything I can do to get out of here as quickly as possible after another weekend of fruitless job searching.
