SAN FRANCISCO, CA - OCTOBER 05: A construction worker operates a steam roller while paving a road on October 5, 2018 in San Francisco, California. Newly released data by the Labor Department on Friday shows that US employers added 134,000 jobs last month with hiring increases within construction, manufacturing and health care sectors. While this was below economists expectations of 185,000, it brought the unemployment rate down to 3.7 percent, the lowest since December 1969. (Photo by Justin Sullivan/Getty Images)
