What jobs a 16 year old get with no qualifications living in the uk ?

Depends what she looks like.

Shop assistant?

what're you doing in the Uk if you're only sixteen.

Restraint or movie theater baby setter there are a lot of places looking for part time help and weekend assistance

why don't you just go back to college and get an education before it's really too late or are you just one of these low life dumb asses who have to rely on other people to live your life and let everyone else do the work for you because your so lazy and you think it's really cool when infact it's not. and do you go roaming the streets and hang out on street corners and have the excuse which other dumbass losers always come up with - 'there's nothing else to do'. always a classic.
gordon brown is right to start charging school college drop outs if they leave education and have no job or whatever as it's people like those who give this country a bad name and reputation and embarasses the united kingdom with this low level of education and intelligence. it really puts this country to shame incomparison with other countries.
don't be a drop out loser all your life - do you really want people looking down on you for the rest of your life? no you don't. you may act the hard nut and think your all that but in reality, your the kind of people who are looked down upon and will get nowhere in life because the jokes on you.
good luck with whatever you want to do.

Hi!

Do you have to have a worker's permit in the UK? You can apply for a worker's permit.

You can work maybe in a restaurant washing dishes, grocery store with helping customers, being a bagger, maybe setting product out on the floor.

Just check with your employment services or go to their establishments.

Good Luck !
