. >> i am kristin schumacher, and i wanted to thank supervisor peskin for bringing this measure but to share some of our union's concerns about what happened in the last session regarding amendments. initially this measure included an early sunset of the payroll tax exemption which was taken out. and our concern is this is a time when the city needs revenue for infrastructure and improving public services and that we shouldn't be chipping away from potential revenues in this measure and our concern is that this will continue in the future and i want to caution the board against that. and the twitter tax break had allowed the companies to avoid over $60 million in taxes and that early sunset of the provision would have meant around $7 million in additional and potential revenue. and considering the size of the tax break thus far, and the impact that the companies like twitter have had on our city i think that would have been fair to include that early sunset. so i want to thank you for bringing this measure but caution against further amendments that would reduce its potential revenue.
