Advocaat/Jurist gezocht voor advies/hulp ivm werk en zwangerschap

Toelichting
First: Im pregnant and I work in daycare, according to the government guidelines pregnant women with 28 weeks or more need to have a replacement of work because of COVID-19. Meaning that contact is more dangerous and need to be avoided. Also, the government states on their website that the replacement of work should be something that it can be done from home. My employer has given me administrative tasks (computer work), tasks that do not involve any personal/sensitive information, however, they want me to do this work (administrative tasks) at the location. Can they force me to go? Although this replacement of work can be done from home? The reason that they gave me is that Im a teacher and I should work in the daycare building and not at home, a reason that I and the trade union think that is not good/enough. Could you please advise me on this?

Second: Can my employer send me to the doctors company (arboarts) after being on sick hours just for one day? as far as I understood they can send me after being sick for a few days/two weeks?

Third: if the job is causing to much stress is there something that can be done?
