Wall Street pointed modestly higher ahead of the first of three government employment reports coming this week which could paint a sharper picture of the U.S. labor situation for the Federal Reserve to consider at its next meeting. Futures for the benchmark S&P 500 were up about 0.3% before the bell on Tuesday, while futures for the Dow Jones industrials inched up less than 0.2%. On Tuesday, the government reports on the number of job openings in February. That’s followed by the weekly unemployment report on Thursday and the March jobs report on Friday.
