Temporary employment means that you work for a short time. Either on a very short contract, or no contract at all. The % of temporary employment has increased in the UK because:
1. Increase in service sector employment, rather than manufacturing sector. Generally, the service sector needs more temporary workers for catering e.t.c
2. Globalisation has increased pressures to be efficient. Therefore, firms are looking for ways to cut costs. One way is to only employ workers when they are needed.
3. More flexible labour markets. Trades unions now have less power; workers are also more willing to take on temporary employment.
4. More women in the labour force. Women are more likely to take temporary employment in between having children.
