Work stress

Au

Does anyone know if drs office would write a note for your job so they don’t change your schedule to something that doesn’t work for you? My job is trying to change my 6am-5pm off wed thurs and Sunday to working 12pm-8pm m-f with like no possibility of getting time off. Meaning I would end up leaving or using all my fmla for my dr appointments cause they simply won’t approve any request. Their way of fixing that would be my trading shift with someone who has the same skill set as me. Which is like no one. This is so stressful! I’ve expressed this to them. My husband and I share a car and going in at 6 is perfect! And really I’m just worried about my time not getting approved due to “business needs”. Open enrollment just started too and if I leave is it even easy to get a job while being like 14 weeks pregnant? Sorry for the long post!
