Some thirty years ago, the late Vicente M. Perez wrote a song in tribute of the employees of Guam's Department of Public Works, to honor all the work they do for the island community.
He gave the song the title "I man ga'chong gi Public Works." Ga'chong means "companion," someone you are with on a journey, or in some event, or staying in the same dwelling. It can also mean people you're associated with in work. So it can mean the gang, the crew and similar words.
