There HAS to be a backstory sometimes, but YANBU @LovelyYellowLabrador At my BFF's workplace there is a man who is 55 and has worked there for 18 years. He is off sick around 20% of the year. And he only does 26 hours a week anyway! Off sick with a bad back, a bad knee, a bad foot, a migraine, a tummy bug, covid (3 times he's had that now!) and a multitude of other things.
He doesn't get paid for being off either. Not for odd days here and there. And he only gets £99 a week SSP for full weeks. He is currently off with a 'bad back' and has been for 5 weeks. No-one knows how his wife puts up with him. 35 years they're been together. She must be a fucking Saint. How she hasn't left him yet baffles everyone. It's also a mystery how they survive financially with him on such low pay, and off sick a fifth of the year! Coz SHE is in a fairly basic minimum pay job (part time too... 18 hours a week!)
In addition, his mother died on Christmas Eve when he was 30 (sad of course, and his dad died when he was 27, also sad) but 25 years later, he STILL uses this as an excuse to have Christmas off. The place is open all over Christmas, 365 days a year, and he says 'MY MOTHER died on Christmas Eve, Christmas is a sacred and melancholy time for me. Very upsetting and hard to deal with.' Dude, she died in 1997, and you're in your mid 50s now with adult children. All the young (usually female) are too scared - for some reason - to challenge him, and allow him to have it off. Every. YEAR.
Also, he posts pictures all over facebook of him at the pub, partying, going on trips and Christmas events, and having a ball with his family. Not very 'melancholy.'
He is off the charts, the laziest, cheeky fucker my friend knows (and me - as I kind of know him too, coz he lives in my area.)
Maybe there is some 'back story' here, but I very VERY much doubt it.
