Tips on working and treatment

Hi, I am off to see the oncologist next Wednesday and I was wondering if there is anything relevant I should be asking around my ability to work? . I work part time in an admin job and my employer is very supportive including offering for me to work from home. They mentioned a couple of months return to work program. I think I will be having 6 cycles of chemo so not sure how that will fit in. I also run my own driving school which I have cut back to a few lessons a week but we are coming up to the busy season and wondering if I can work this in with my chemo? or am I too optimistic that I will be able to do that?  I had a mastectomy 3 weeks ago and have been told I will need chemo then radiotherapy for 28 sessions after chemo finishes.
