Trying to keep this as brief and objective as possible
Married couple, both work full time, 1 dc(5) expecting dc2 later in the year
Person A works in an office based role, has been wfh since March last year. Will be going back to the office 2 days a week from July time. Generally works 9-5, sometimes logs on a bit earlier, lunch breaks are either 30 minutes at lunch time or used to do pick up for dc.
Person B works in a shift based role, a combination of earlies, lates, nights. Unable to work from home. Very much goes in for their shift start time and will not stay late unless an absolute emergency. Generally works a 4 day week. Has 2 full weeks off every 8 weeks.
Today Person A Has been working as usual, Person B has been off. Person B has asked several times what jobs need to be done around the house, not much to do so has sat and watched TV/tablet all day. Then picked dc up from school and they went to an an activity. Usually cooks dinner when off.
Person A was running a few minutes late finishing work when Person B and dc arrived home from activity (think 5.08pm) Person A was logging off and shutting laptop down. Very rarely logs off dead on 5pm, but is usually out of the dedicated room in the house that's an office by 510 at the latest.
Person B has moaned that Person A was late from work and could have finished on time and started dinner and now that means they have less family time.
Person A argued that Person B could have prepped the veg etc before going out seen as they had been off all day.
Person B has also moaned that Person A is never finished dead on 5, works too hard, cares about their job too much and prioritises their job over the family because they may start 5 minutes early and finish 5 minutes late.
Person A Has tried to point out that they are saving 45 minutes each way on commute so dc doesn't have to go to wrap around care before or after school so is fully available for school runs even when Person B is on shift.
Well done if you made it to the end!
