Earlier this year, San Francisco Mayor Gavin Newsom ignited an open source movement in government when the city approved the nation’s first open source software policy. Now, another movement — labor may be getting behind this effort. I have been asked to speak with Local 21 of Professional & Technical Engineers (IFPTE/AFL-CIO) today about Gov 2.0 initiatives I helped lead for Newsom and why unions should embrace open source technology.
