After having saddled Philadelphia retailers with that onerous sugary drink tax last year, Mayor Jim Kenney signed an ordinance into law this week that bans employers from asking job applicants about their salary history.  The law, which also has been adopted by a host of other cities and a handful of states, is known as pay equity laws with the theory being that since women have historically been paid less than men, salary histories could serve to perpetuate that inequity.  Councilman Bill Greenlee sponsored the bill and cited Massachusetts enacting pay equity laws last year as his inspiration to file it in Philadelphia. The bill passed the council unanimously back in December. A little different case in New Jersey however, where Governor Chris Christie conditionally vetoed pay equity bills last May. This week, the legislature sought to override those vetoes, but came up short by 4 votes of the 27 needed to override in the Senate. Christie had previously vetoed similar legislation in both 2012 and 2014, both times his veto was upheld.
