From a Wall Street Journal piece today, headlined “Besides the FAA, Furlough Impacts Are Mostly Muted”:

WASHINGTON—President Barack Obama warned in March that across-the-board budget cuts would lead to significant pay cuts and furloughs for “hundreds of thousands of Americans who serve their country.”
The layoffs finally kicked in this week – most notably at the Federal Aviation Administration, where furloughs of air-traffic controllers led to flight delays – yet many agencies have found ways to make the required savings and have spared government worker paychecks.
Agency chiefs, under pressure from the public and federal-employee unions, have cut travel and contractor spending, trimmed office hours and delayed some furloughs, achieving dramatic reductions from some of the dire predictions officials made earlier this year.
