street protest occurring in front of a Banco Bi-o building

street protest occurring in front of a Banco Bi-o building. A group of people are walking down the street, some carrying a large red banner that reads "Sindicato Unico De Luz Y Fuerza." Most of the protestors are wearing casual clothing, with some in work attire. Some people are wearing hard hats. The weather appears to be overcast, and the street is wet, possibly from rain. There is a tree next to the bank building, and other buildings are visible in the background. The protestors seem to be moving toward the camera.
