Dd does a load of zero hours contract jobs. I doubt she could do a 9-5 job 5 days per week.
There are a few where you are tied to the one employer which I wouldn’t touch with a barge pole but for the ones where you can pick and choose your shifts you can pick up loads of work.
Personally I would have him home with the understanding that he has to get any type of job going do he can save to go travelling.
It might be too late now as you have already answered him when he said he wanted to come home.
I think he might not have come home, he was just asking to see if there was a back up. Sometimes people just want to know what options are available.
Regarding careers advice. I was very hot on finding out what dc wanted to do so we could gear their education etc to the general area to do with that career.
Dd knew from being quite young what she wanted to do and she now has her own business. (Still works doing umpteen other things to bring the money in).
Ds though hadn’t a clue. It got to the stage where I did his horoscope at one point.
We started off asking the questions Did he want to work indoors or outdoors.
Which area did he want to pursue.
I.e Sport, Construction, Academic, the Arts, IT, Office work, Retail, Manufacturing, Engineering, politics etc and from there we listed literally 1000s of careers. Printed them all off
He went through them and crossed out those he had no interest in.
He would look up some things and make a decision about what exactly the job involved.
Until we came down to 3 areas. He completed his first year of college after 2 terms. Average score in all tests and assessments of 97.5 %
He just finds it so easy to do. He was struggling at school. Once he found his calling he was a different person.
I wish schools would have a lesson each week in Careers advice where children can actually think about what possibilities are out there and would they suit a career in the service industry running a night club rather than ending up shuffling papers around an office desk for the next 5 decades
