For later, if worst comes to worst, some of this might be useful longer term (and based on how things work here in Oz, not sure if they are the same there)
Talk to your local Domestic Violence Service or Crisis Service (whether run by the Red Cross, Lifeline, whoever). They might be able to help with:
1) emergency payments from your statutory / government authority. You might not need cash right now, but if you get cut off, you'll still need food / petrol / other essentials. Not sure if / when you would be eligible for them, but worth an ask. Also be aware of charity organisations. Yes, I know some people won't go to them, but they are there for a reason. Some even do short term loans to help people get by. If it isn't a loan, but a grant, you can always keep a record of what you receive, and pay it back / make a donation later.
2) referral to legal / workplace services so you can ensure that you get your entitlements
3) free / temporary / cheap accommodation. Staying with friends can go for so long, but also sometimes if you feel you're imposing or need some time away from them, there might be options out there for you whether short or longer term.
4) access to free / minimal cost counselling. The three of you need it. Regardless of what happens. You also need some constructive debriefing after today. Again, friends can do so much, but trained professionals can also provide referrals or alternative strategies / supports.
5) if you aren't getting kicked out / fired today, start planning an exit strategy.
As I have grown older, I've learned that pleasing everyone is impossible - but pissing everyone off, is a piece of cake.
