Fake fracture excuse at workplace?

Pls share how many have shared a fake medical certificate for fracture at their workplace and taken wfh? Was it too much to ask for? How did you tackle pestering questions Backdrop- my office team are literal sickos and have been treating me horribly since i had a baby. There’s a policy for wfh for new moms who are still breast feeding however they granted me only 3 months. Also team lead not allotting any work due to year end blah blah but expect me to come and sit at office everyday from 9-5. My baby is still on my milk and I’ve started the weaning process. I just need the salary for another 3 months and I’d then put down my resignation …. Please help 😥😥
