Job 1:
Part time hours that fit well around school and home life. 2 hours commuting by train each day. Total hours out the house each day - 8.
Job role itself sounds quite boring and something you wouldn't enjoy greatly.
Job 2:
Full time hours, zero flexibility to work from home. Between 2 and 3 hours driving each day in total. Probably out of the house for 12 hours each day. Household name company, great place to work with a job role which you think you'd love.
You're a single parent so job 2 will probably involve needing an au pair.
Which do you choose?
