WASHINGTON (AP) — America’s employers added a healthy number of jobs last month, yet slowed their hiring enough to potentially help the Federal Reserve in its fight to reduce raging inflation. The economy gained 315,000 jobs in August, a still-solid figure that pointed to an economy that remains resilient despite rising interest rates, high inflation and sluggish consumer spending. Friday’s report from the government also showed that the unemployment rate rose to 3.7%, up from a half-century low of 3.5%. Yet that increase was also an encouraging sign: It reflected a long-awaited rise in the number of Americans who came off the sidelines and started looking for work.
