My first thoughts about your post, were, it's not your concern, but i can see from further posts, you come from a caring place about your SD.
Young people are so different with their individual attitudes to work.
When one of mine was 16, she looked for a job the day she got her GCSE results and got a job within a couple of weeks. She likes the finer things in life and knew she had to pay for them.
My other daughter, had no real desire to get a job, until she was going on holidays with her friends after their A levels, then she knew she'd need the money. I initially asked her to think about being a job, but she wasn't interested.
If your SD wants things that cost, then she'll be motivated to get a job.
Both went to university and had jobs at various stages, but the one who got a job later, was less inclined to work. She isn’t a fussy as her sister and doesn't buy as much, so she preferred to not work and focus on uni work.
We later discovered that's she's dyslexic and it takes her longer to process things as well. She struggles to be organised and had ADHD traits. I think this contributed to her not wanting a job, as she struggles to do more than one thing at a time..like work and study. Her room can be very tidy, then a terrible mess the next day.
Some of this may apply to your SD.
