work something in with something—make smth. such as a schedule, etc. fit or harmonize with smth.:
- I’m motivated to work out and feel better, I just don’t know how to work it in with everything else I have to do.
work something into something—
1. force smth. into smth. else by gradual movement:
- He was able to work his foot into his boot but it was still very tight.
2. include smth. into smth. written or spoken:
- Each week I try to work a few jokes into the typically mundane legal topics we discuss.
