If you are given a student visa when you enter the UK, you are allowed to work part-time. The cost of living in the UK (for example, accommodation and food) is quite high, so many students want to find part-time or holiday jobs so that they can afford to stay longer. Employment opportunities exist: unemployment is quite low in many parts of the UK, and there are shortages in certain professions such as nurses and teachers. Voluntary work has a long history in the UK and is usually well-organised. The number of holidays people can take is quite high compared to some other countries, and members of staff are usually encouraged to take them.
