Different uses different widths. If you are installing a service walk around your garage, or similar area 24" wide is adequate. A front walk or an area where people walking in opposite directions will occassionaly meet should be 36" wide. A comfortable sidewalk where 2 people can walk side by side should be 60" wide.
ADA requires 36" minimum with turnouts for passing every 200', otherwise make it 60" wide without the need for turnouts.
While you are here lets talk about sidewalk thickness. Sidewalks should be 4" thick, but quite honestly most contractors use a 2x4 to form the sidewalk so they wind up being 3 1/2" thick, which works fine. If you will be driving a car or light truck over a section, increase it's thickness to 6"
Note these widths will work with all residential applications. Some commercial applications may require wider and thicker sidewalks.

Private walks typically 3 ft wide. Public walks, 4 ft wide but vary by municipality and handicap accessibility.
If you made a sidewalk about 2.5' wide it would be about 13' long.
The width of a normal sidewalk typically ranges from 4 to 5 feet, allowing enough space for pedestrian traffic. However, in some areas, sidewalks can be wider to accommodate increased foot traffic or outdoor dining spaces.
You should always be respectful when talking to your boss. It is not respectful to spit on the sidewalk.
