Theme Day - Empty
My company observes 'Lights Out Friday' which means we turn off lights in areas with plenty of natural light (we have recently upgraded to Lights Out Wednesday thru Friday because of the increased price per kilowatt from .18 to .38). Personally, I don't mind. The fluorescent lights bother me. While most of my co-workers agree that it makes sense financially and to reduce our carbon footprint, several of my co-workers don't really like it when the 'lights go out in Georgia'.
Post post clarification: We are not totally devoid of light. We do have task lighting in our cubes and we can bring in desk lamps if we need them.
