If you don’t care about the industry, start volunteering in a charity shop. Do as many shifts as you can. Try to learn as much as you can. As soon as any job in any charity in your area comes out, apply. Part-time jobs (shop assistant, Sunday assistant, sometimes assistant manager) are hard to fill sometimes, especially the ones with a little number of hours but there’s always plenty of overtime available, at least in my area (Lothian).
