This report measures the change of a country’s employment conditions from the previous month. In laymen terms, it means it counts the total number of people who lost their jobs or gained employment in the previous month. A negative figure means that overall, more jobs were lost than gained in the previous month, while a positive figure means more jobs were created than lost.
The markets monitor employment because it is directly related to consumer spending. Naturally, people would be more willing to spend if they were employed and vice versa.
