@UpDownRound ‘I had it hard so you should have it hard too’ 
The ‘advice’ you have been given on this thread is shocking @M2B91 - I ended up reading lots about this as I am now in my second trimester. I also got in touch with my union and sought their advice.
Your workplace are legally obligated to have completed a risk assessment taking Covid into account. It is also the responsibility of your work place to mitigate the risk from Covid as much as possible. This could mean a number of things. If they can’t mitigate the risk adequately they have to adapt your role/offer you wfh or you can be signed off on full pay.
I would advise that you ask for a new risk assessment to be completed ASAP, taking covid into account. Your risk assessment should be a working document and should be updated/checked monthly. You could also get in touch with your union and your midwife and ask for their advice.
You should also ask to see the schools risk assessment with regards to Covid whole school- they should have a section on pregnant employees on there and school policy. Most schools current policy is that, if unable to socially distance, pregnant women should be working from home from 28 weeks onwards.
The union advice is currently;
NEU;
Pregnant women of any gestation should not be required to continue working if this is not supported by the risk assessment that employers are legally required to undertake.
Although it is an individual decision, vaccination is the best way to protect from the known risks of Covid-19 in pregnancy for both women and babies, including severe illness and pre-term birth (Having a vaccination does not, however, remove the requirement for employers to carry out a risk assessment for pregnant employees).
Pregnant women who are unvaccinated, or not fully vaccinated, are at greatest risk. Employers are urged to consider how to maximise the potential for homeworking for this category and should allow paid time off for staff to receive vaccinations and boosters where necessary.
The joint union position is that, although it is not a Government requirement, until more is known about the effects of the Omicron variant, it would be prudent for settings to permit pregnant women, of whatever gestation, and vaccination status to work from home. For some staff that may mean agreeing to a temporary re-deployment to other duties that can be undertaken from home. Where this is not feasible, or a pregnant employee chooses to be in the workplace rather than working from home the risk assessment should take account of the factors set out in point 2 above.
NASUWT;
‘In respect to women who are pregnant and in their third trimester (more than 28 weeks’ pregnant), advice and guidance produced by the UK Government expects all employers to take a ‘more precautionary approach’, particularly as there is evidence which suggests a link between the symptoms of Covid-19 and complications in and around the time of birth, including premature birth, pre-eclampsia, the need for an emergency caesarean, and stillbirth.
Those who are pregnant and in the third trimester should therefore still take care to minimise contact with others from outside their household and should only return to the workplace if it has been demonstrated that it is safe to do so.
Whilst advice from the Department for Education (DfE) advises that pregnant teachers who are clinically vulnerable can follow the same guidance as everyone else, there is an expectation that schools adopt the ‘more precautionary approach’ referenced above as part of any risk assessment for those who are pregnant and in the third trimester.
This includes consideration of how best to redeploy teachers who are pregnant and in the third trimester, including adapting duties and looking at how to maximise the potential for working flexibly from home/homeworking.
