Volunteer

There are lots of volunteering opportunities in Ireland, long or short term, and abroad. The web is a good place to start searching.
In Ireland, Volunteering Ireland, Activelink and the Citizens Information Board have online databases and specific organisations e.g. Irish Refugee Council, Dublin Simon Community, or the ISPCA need volunteers to work with them from time to time.
Abroad: organisations such as Action without Borders, Suas Educational Development, OutReach Moldova and Timebank offer opportunities. Often you are required to fundraise a specific sum of money.
Voluntary organisations operate like any business, with administration, research and fund-raising areas.
Unpaid work may be the only options if you are keen to get experience in areas such as media, advertising or PR, where paid summer placements are limited.

See Resources (Voluntary Work) for links to all the above.
