News Summary: Unions strike across Argentina

ROLE REVERSAL: Argentine President Cristina Fernandez faced a nationwide strike led by union bosses who used to be her supporters.

ISSUES: Truckers union head Pablo Moyano and some other labor leaders broke from Fernandez this year after she supported a rival slate in union elections.

PROTEST: Strikers want to eliminate income taxes and gain salary increases and benefits. Most union workers won pay hikes of 25 percent or more this year, in line with what private analysts say is Argentina's true inflation. Those pay hikes put many over the threshold for income taxes.
