I guess you have to make your own fun at work, even when work is 20 stories off the ground on the skeleton of a future skyscraper. But these photos of construction workers enjoying their breaks and photo-ops high in the air are simply terrifying.

Of course, not all of these photos show workers goofing around. Some of them are just doing their jobs. Their scary, vertigo-inducing jobs.
