Police officers stand guard outside the Greek parliament during an anti-austerity protest in Athens, late July 17, 2013, as Greece's shaky coalition government scraped through a vote on a bill to sack public sector workers. The bill includes deeply divisive plans for a transfer and layoff scheme for 25,000 public workers - mainly teachers and municipal police - that had triggered a week of almost daily marches, rallies and strikes in protest.
