Asking as no context has been provided – why has the doc recommended wfh? Are there any medical complications like placenta previa? From what my doc had told me, these often get resolved after 1st trimester.
Either way, if doc can give their recommendation in writing, mail that to HR / department head say given thereโs a wfh policy, please approve or provide alternate solutions on mail. She should not be taking LWP. Also, preempting HR to try and push her out as low performer. So gather all appreciation mails, appraisal / feedback documents that indicate no performance issues and have them ready.
Would strongly recommend consulting with a lawyer f2f. If HR is still playing hardball, itโll work in your favour to be prepared and show that youโve already consulted with lawyers.
