The specific job duties of all Color Specialist, Color Shaders, and Lab Assistants require that they must remain in the RCC lab. Their work is centered on mixing, spraying, and developing colors. While performing their tasks, they must have constant, unhindered, and unfettered access to, and support from, the Regional Color Coordinator, Lab Supervisor, and Color Service Representative. Breaking a link in this chain by moving any of the components to another location will negatively disrupt the smooth operation now in place.
