My wife and I both work for the same company. She is part time and I am full time.
We have little to save after paying utilities, a mortgage, fuel twice a fortnight, and food shopping. Also any work needing done around the house or medical needs cut into our savings.

Fuel is expensive, so we can pool to work together, even though she works night shift sometimes and I work in the daytime. So we both stay back or wait early in the morning for each other, taking up extra free time that could be spent more productively.
