Age 16 - "costs junior" (costs was the accounts department) at a solicitors firm, I then somehow got conned into changing jobs to "office junior" in total I was there for 3 months or so before being sacked for being late 3 days in a row (I had to rush my dog to the vets 3 times, first time for a massive cut on her leg, the second/third time because she pulled the bandages off I was an hour late each time). I was also doing 2 college courses in the evening so I decided to go back to college full time and had a job working in a spar (small supermarket) for all of a week before I told the manager to shove his job up his butt for the things he said to me.
Age 16 - Got a job in "telesales" selling conservatories, the manager was so dodgy I worked there for a week before he said I wasn't selling enough (despite making 3 sales, which surprise surprise fell through so I wouldn't get my commission). He messed me about tried not to pay me, I kept going back asking for my wages, the web design company on the next floor gave me a job (I think the manager felt sorry for me) it was only a few hours a week.
My mother got into financial difficulties (couldn't pay her debts) so I gave up my part time job and college to get a full time job to pay them for her, working as an "accounts clerk" for a pharmaceutical company, I was 17 by then. I was too efficient, finishing my work by lunchtime so they had me covering reception, then I had to help out the other departments, then they had me doing a course on importing and exporting (as well as an accountancy course) then they made me redundant. I worked for them for about 6 months.
I got another job straightaway (finished the last job on the Friday, started the new one on the monday) again in accountancy, this time as the sales clerk. Again too efficient and I started helping out other departments, then the other 2 people in accounts got pregnant and they hired one person to cover the finance director and I was left to run the rest of the accounts department. By then I was 20 and had worked for them for about a year when I told them I was leaving to move 300 miles away.
That's it for me, I've done a few uni courses and built a few websites to keep me busy but no real job.
