Stressed any advice with be helpful

[Vashi]

Hi,

I am employed with a company in London for past 1.5 years with an initial contract of working 3 days from home and 2 day in office. Meanwhile my OH got an opportunity and we moved to South-West of England. At this point my company changed my contract to 4 days WFH and 1 day in office. It's a 6 hrs commute in total on the day I go to office.
Some structural changes happened in the company in past 2 months but nothing was reflected in my role or responsibilities. I got pregnant and shared the news with the manager as I was getting morning and evening sickness and had to call sick a few times.
Had a meeting with manager yesterday where he is asking me to come to office for all 5 days knowing the significant amount of commute that I have to do. I have a few more meetings in coming week with the manager and HR for this setting.
And I have a feeling if I say no to 5 days in office they are going to make me redundant.
Can you suggest what rights do I hold at this point? And where can I seek help?

Have they told you the reason for the chance in pattern?
From experience, it depends on your contract. What does it say about WFH & in work?
If your current pattern is in the contract, it can be changed by then but you have to be involved in a consultation for them to make any changes.
Also it must be for a reason (do they have one? )
Citizens Advice probably your best bet?

How far along with the pregnancy are you? Just thinking that by the time that they've consulted and given you notice of a change to your working pattern that you may be near to going on mat leave anyway.

Do you have anything in writing that describes your working pattern as a formal arrangement? I'd definitely seek advice from Citizens Advice, ACAS, Maternity Action or similar
