I think the answer is no, but let me poll the experts. We had an employee take off about 15 days last month. I tried to get her to submit the request for FMLA but she never did and her boss kind of let it slide. She took another three days off last week (After a lot of research, I now know that we can initiate the leave; which is my current plan) however can we say those 15 days last month will also count towards the leave?
She had a serious medical condition that we thought was over, which is why we really didn't push it last month. The three days taken last week are new symptoms to this condition, so it's all related. We want to protect ourselves and her going forward.
