I work an office job, Mon-Fri 9-5, £26k. I was previously a supervisor in my current department but my mental health couldn't cope with it so I stepped back down. I am so much happier now and have no ambitions to step back up. My job allows me to clock off at 5 and enjoy my life without worry or stress. I could earn another £3-4k if I chose but my happiness is more important.
My wife worked in a supermarket when we first got together, then switched to working in a care home just before Covid struck. She worked relentlessly through the pandemic, despite hating every moment of it. Last year she'd had enough and we agreed she would hand in her notice, without having a job to go to. Her mental health was more important to us, even though we knew that we would struggle a lot without her income. Luckily she got a job fairly quickly, she earns £20k and she is HAPPY! She occasionally has the choice of overtime, maybe one weekend a month, which she does and adds to our savings account.
Basically, we could both choose to go and find jobs that earn more but we are happy. We both finish at 5pm and can spend our evenings/weekends together. We don't want foreign holidays, prefer holidays in this country with our dogs. We both want the same in life.
I would rather be without someone that is happy in their life and wants to spend time with me, than someone who earns more but spends all their time working.
