How many weeks pregnant r you?
Normally for shift duties, it depends on how you see it... I used to have a colleague, she was pregnant, but worked till she gave birth, she was on shift duties, she worked in F&B industry, she got to stand and walk around, and that helps as walking is healthy excercise for baby
However, after giving birth she gave up her job to find normal working hours so tht she could be with her baby at night
How about you? which industry r you at? and how long is your shift duties? if it is split shift, then it is not good, you might want to change to normal hours.....
