Kat's reaction wasn't what I expected. She seemed a little upset that I would be working more hours. I tried to tell her that this isn't a bad thing. Sure, it's more work, but it's going to allow her to take the time off she needs, and in the long run, it will help me at my day job. I have no mamagerial experience in my chosen profession, so this little bit of added responsibility will help me with that, and may even turn me onto new career opportunities (no, I don't want a career in retail management). Bottom line is that if my day job or my home life starts to suffer adversely, I'll drop the supervisor role like a hot potato, cut back my hours, or quit outright.
I want to be able to provide for Kat, and I don't want her to feel the slightest bit bad for the work I choose to do so. I hope I'm making the right decision.
