We Are the Union have announced an indefinite hiatus. They said just this:
We've decided to take a hiatus from active status. […] We were a band. Maybe someday we will be again. We've had some amazing times, and we truly appreciate those of you who've contributed to our existence. We've never been a supercool hype band or uberpunx beardy band, so we thank each and every one of you who listened to our music over the years.
The band last released You Can't Hide The Sun in 2012
