Athens, Greece (CNN) -- Greek workers were holding a one-day strike Wednesday to protest government efforts to stave off a financial crisis.Thousands of public-sector workers and their supporters began the 24-hour walkout at 9 a.m. (2 a.m. ET), though local media said workers at Athens' main international airport began their strike at midnight.Government offices, courts and schools were closed, though public transportation largely continued to operate.The umbrella civil servants trade union ADEDY, which called the strike, said most of its 500,000 workers were on strike, though that number could not be confirmed. When strikes are called in Greece, non-union members often will join those on the picket lines.
