cyclical factors?

Question

does anybody know what cyclical factors are?
Here's the sentence:

Although the increase in non-regular workers has been partly caused by cyclical factors, there is a risk that labour market dualism will become entrenched, given that thus far only a small proportion of non-regular workers have become regular workers.

Answer 1

Cyclical refers the alternating booms and recessions in the economy, that is the business cycle. It is misnamed because it happens at irregular periods not regular ones as the name implies.
