Very helpful thank you
You legally can’t discipline a pregnant employee for pregnancy related sickness you’re protected by the equality act. If you’re off sick within a certain period before due date they can start your maternity leave early but that’s very much later on down the line and if you’re contracted then you won’t be going on maternity leave presumably!
No they can’t dismiss you based on illness, unless there is something in your contract that states otherwise but generally sick leave can’t be penalised, though may be paid at stat. Would just make sure you have any required medical notes and open communication with them. They should be carrying out a risk assessment each trimester. Obviously some may miss the first as won’t have told yet but sounds like they are aware. You could also request working from home, they don’t have to agree to it but should consider especially if temporary and you could work in this way. I think I would meet with my manager/HR and clarify sick leave/pregnancy rights under your contract. Generally though pregnancy is pretty well protected.
