Unemployment in Zambia was 16% in 2005 according to the Zambian Central Statistical Office. The agriculture, forestry and fisheries industries employ over 70% of Zambian workers. The legal minimum wage for nonunionized workers equates to around $16.50 83,200 kwacha per month. Most minimum wage earners supplement this through subsistence farming. In practice, almost all unionized workers received salaries considerably higher than the nonunionized minimum wage.
As for tourists, temporary work is likely to be difficult to secure. Although there is a substantial expat community in Zambia, most of these individuals are contracted by international agencies; by and large, they did not come to Zambia and then find work. Persistence and connections might pay off, but outside of the few hostels or Western-oriented bars, a tourist should not expect to find ready employment.
The University of Zambia is the official university. However, it is not affordable for most Zambians. There are also Technical Schools throughout Zambia, and Teacher's Training Colleges are found in each Provincial Capital, providing two year's coursework for about $300.
Northrise University is in Ndola. As a private university, it focuses on business, information technology and theological study.
For tourists, the biggest educational experiences would likely be:
Visit a game park and learn as much as possible about the area's animals from the guides. Guides can be an incredible source of information. Remember to tip them.
Arrange for an overnight stay in a "Traditional African Village". Of course, because the locals have prepared for you, it is no longer 100% authentic, but you will get an idea of the hardships Zambians face.
