America’s employers extended a streak of robust hiring in March, adding 431,000 jobs in a sign of the economy’s resilience in the face of a still-destructive pandemic, Russia’s war against Ukraine and the highest inflation in 40 years. The government’s report showed that last month’s job growth helped shrink the unemployment rate to 3.6%. That’s the lowest rate since the pandemic erupted two years ago and just above the half-century low of 3.5% that was reached two years ago. Despite the inflation surge, persistent supply bottlenecks, damage from COVID-19 and now a war in Europe, employers have added at least 400,000 jobs for 11 straight months.
