I was just thinking about when I went through similar and it occurred to me that you will be required to see the Work Cover insurer's psychiatrist.
Here are some points to consider when that happens (happens in bullying cases because you're claiming stress due directly to the work situation):
- if they choose one more than a 10 minute drive from you, insist on a taxi to get there and they can put it under their 'ambulatory' costs, which means the cost to get you to travel to a medical practitioner, because it's work-related. I had to go to one and I didn't have a car, it would have taken too long to get there by public transport and we had a new puppy that I wasn't going to leave for that length of time. They ordered me a private taxi (a sedan sized limo!), and I warned them that I'd have to bring the puppy with me (even on private transport it was going to take an hour to get in from where I lived). The driver was very nice and said he drove a lot of stress cases to the psychiatrists for the insurer. He was very nice!
- Your GP costs can be put under this claim, too, so don't be afraid to go to your GP again - the insurer pays the costs, that's what the premiums are for. Get the address of the insurer, a contact name (or the HR person at work, if that fails) and get the GP to send the bill to them - don't handle any more invoices or bills.
- The psychiatrist they send you to is not concerned about your welfare. Tell them the bare minimum and keep it work-related.
- The psych WILL probe and try to get you to reveal about your private life, and will likely push buttons about the pregnancy - be prepared for this and stand your ground, keeping him or her at barge-pole distance. Always link the stress in your head with incidents at work. If you must mention your DP, only say that he is supporting you and looking after you while you fall apart about work issues. If you say that the stress has caused strain on your relationship, or things like that, they will twist it to mean that your personal life is what is causing your work troubles. I thought I was helping my case by saying my DP was exasperated with how work was affecting my mental health and it was used against me, quite inexplicably.
- The psych is paid by the insurer to say that you are NOT stressed due to work, so give him or her as little reason to conclude this as possible. If they ask about anything outside of work, say that it has nothing to do with the work stress and you just want to return to work without the pressure to resign. Be specific about that. Do role playing with DP if you have to!
- You will need to really play up the stress and probably cry when you talk about how much you want to keep working there because you like the work and are good at it, but actions of your boss make it impossible to switch off after work, because you go home and worry about how much they're going to pressure you to leave, and the effect on your baby's cortisol levels (because cortisol is a hormone that crosses the placenta).
- You owe the psych nothing, remember that golden rule!
- Don't give anyone else at work any personal details, close shop and pull the curtains - trust is broken and even a joking comment can be used against you.

I hate that I've had to remember this, and if someone had told me before I'd gone in I would have been very grateful. I've given these nuggets to a friend and also my mum and they found it very useful, even though at the time of the telling they thought I was overreacting. I wish I had been. My friend was successful in her claim against the Dept of Justice, too, on the upside (well, downside, depending on how you look at it).
Most stress claims aren't successful - they tend not to believe you're stressed until you are completely broken. I will say, however, that my girlfriend was NOT completely broken and hers was successful. Plus, there were people back in my time working towards changing that situation of having only suicidal and heavily medicated workers' stress claims being accepted. So, I hope that holds true for you. The 'joke' was that if you weren't already stressed when making the claim, proving you are stressed would send you to a psych ward
Don't let that deter you. You can do this. Push it as far as you possibly can, and do pull back if you feel you have reached the point where it's not worth it anymore - only listen to your own voice on this, as there will be plenty of people who will try to tell you it's not worth it before you feel ready to pull out.
Make sure your baby gets plenty of your feel-good moments - yoga will help, listening to mantra music before bed and while you drift off, and at any other given time listen to things that will relax you (more so than things you enjoy, I mean specifically relaxing listening).
Sorry to harp on about it!
