Returning to work 3 weeks postpartum

Long story short my husband was arrested last week for an absolutely absurd reason. He spent three days in jail and while he was incarcerated I had to go to work at our pet service business so that it would still be running smoothly. I was three weeks postpartum and am currently breastfeeding. Now that he is back home, him and his FAMILY are volunteering me to go back to work and he is also acting like it’s expected of me. Baby is a month old now but I’m thinking this is complete bs... I don’t feel like I have a say bc I’ve voiced my opinion and they are still expecting me to go back. I’m tired, stressed, and now very disappointed. If I go to work our baby will tag along with me and stretch the process out which means I will be there four about 4-5 hours. What would you do? Play nice and just go do what they expect? Or do what I want and just stay home with our baby? Grrr.....
