A woman’s place is in the lab – even if she is pregnant

It makes sense to provide a 'reasonable accommodation' for ANY student who cannot participate in an activity due to a temporary or permanent condition. In my time I have served as an amanuensis for someone who damaged their writing hand just before an exam (poor examiners, my writing's dire!), taken exam papers to students' homes when broken legs or indeed advanced pregnancy made it difficult to get in to sit them, and had students direct someone else (or myself) in doing physical work in a computing laboratory when teaching networking - the class had to demonstrate that they could hook up a network physically, and that's difficult if for whatever reason you have limited mobility. But that was me... as the relevant tutor. I'd organise stuff and tell the institution how I was handling it. Surely whoever was running the chromotography class could have provided a solution - perhaps draft in a graduate student to help, or pair the pregnant lady with another student who could handle chemicals safely.
