Hiring is expected to jump in the U.S. service sector in April when compared to the same month last year, but not in the U.S. manufacturing sector, according to the leading indicators of national employment report released today by the Society for Human Resource Management.

The report’s survey found that 49.4 percent of service-sector companies plan to hire in April while 7.6 percent plan to reduce their workforces for a net increase of 41.8 percent. That compares to a net increase of 20.1 percent in April 2012 and is a four-year high hiring rate for the month of April.

However, 50.3 percent of manufacturing firms plan to hire in April while 12.5 percent plan to reduce their workforces for a net increase of 37.8 percent. That compares to a net increase of 43.3 percent in April 2012.

Data for this report is collected through a monthly survey of human resource executives at more than 500 manufacturing and 500 service-sector firms.
