If you think your daughter is anxious about you going to work, maybe you could make a special routine that will comfort her before you go, during your absence and when you return.
I always had breakfast with my son even if it meant getting us both up early. It is some of my fondest memories. MY middle son used to get "lips." That meant I put on my reddest lipstick and kissed him on his hand. He had my kiss to carry around with him all day.
There is a book called The Kissing Hand that is sort of like this. It's a perfect story for little kids suffering from separation anxiety. You two could read it together at bedtime.
When you come home, maybe she could share your dinner with you even if she already ate hers. Let her sit with you and share what is on your plate. That was also a big deal to one of my kids.
I would remind her, but would not make a big deal about the accidents.
Best of luck.
