U.S. employment gains likely slowed in January as the boost to hiring from unseasonably mild weather faded, but an expected rebound in wages and a steady jobless rate will suggest the labor market recovery remains firm. Nonfarm payrolls probably increased by 190,000 jobs last month, according to a Reuters survey of economists. January employment will also lose the lift from the hiring of couriers and messengers, which was buoyed in November and December by strong online holiday sales.
