Pay raises are getting smaller, but consumer prices continue to rise. If the trend in shrinking worker pay raises continues, it could mean stalled consumer spending and a halt to economic growth.

Earlier this year, some 20,000 salaried workers of Ford, mainly in the United States and Canada, got their first hike in base pay in two years. It wasn't much: a raise of 2.7 percent, on average. But the Dearborn, Michigan, automaker threw in some bonuses in 2011 and again this year.
