With the downturn in the economy some companies are instituting a work furlough. Unpaid time off, with a guarantee to return to work. Most furloughs are 1-5 days off a month. Furlough envy is when someone is jealous of someone else's unpaid time off.
Dude, did you hear Jack's company is doing a 10 percent work furlough? Damn, that's fucking sweet. I've got a bitchin' case of furlough envy.
