I work as bank staff. I'm on Saturday and Sunday this week as partner is off. There's now a bus strike on Friday and he wants me to tell work I can't do Sunday as he wants to switch his days. I said no he can walk to work on Friday 45mins/1hr or try to pre-book a taxi.
He has previous for being a selfish prick at times, but apparently I'm being selfish by not giving up one of my days. He earns more but it's hard for me to work around the kids nursery times so the weekends are the only days I have. His job is more hands on whereas mine is more reception based.
