Remarkably, the average employed American worker gets 18 vacation days but uses only 14. Are you kidding me? Collectively employees forfeit $68 billion of time. That’s just crazy. Yes, it’s a tough job market out there. But show your dedication by working hard when you are supposed to–not by volunteering time to your employer. If you just can’t relax, use the days off to moonlight for more income or to sell stuff out of the attic.
