I’ve told this story a few times on here.
I worked with a guy who had a baby girl with his wife. She had a difficult pregnancy and he had a lot of time off. People bent over backwards to help him/cover shifts etc. Shortly before the baby was born we did a big collection and bought a big ticket item (that was generally the way - we were a close team and the bosses were generous) for them.
After she was born he brought her in and sometimes when his wife was struggling he’d bring her in when he was working and people would keep an eye on her in the break room.
When she was only a few months old he came in, in tears and said his wife was pregnant again. He was upset because his wife wasn’t coping already, but couldn’t face a termination. Over the duration of the second pregnancy he had loads of time off. He changed shifts, people covered for him, people babysat and everyone did everything they could. He announced the birth of a second baby girl and because he had said they were skint the second collection was given in cash (nearly £700!).
For the next three months he had time off, left early, came in late and made excuses about not bringing the new baby in to see us (blamed his poor wife by saying she was over protective etc).
Then someone new started. She mentioned where she worked before, he went as white as a sheet and walked out at lunchtime. Didn’t come back for a week.
Turns out the second pregnancy and baby was a complete lie. He’d just realised in the first one how much free time off he could get. He had planned to say she miscarried, but then another girl on the team did miscarry so he felt bad and waited. Then waited. Then felt he had to continue with it.
Bosses sent him for counselling and expected people to accept him back!! Eventually someone said they felt the acceptance of the collection was basically theft so the bosses said they’d look into transferring him to another office.
Eventually when someone realise that him claiming paternity leave, and then claiming the money for it from the government, was actually a fraud thing they sacked him in case they got in trouble.
I have suspicions that lots of other things about his life were massively exaggerated or outright lies as well.
