Freedom.

There is a real freedom of speech on a job site, which reverberates outward and sustains a wider liberality. You can tell dirty jokes. Where there is real work being done, the order of things isn’t quite so fragile. Not surprisingly, it is the office rather than the job site that has seen the advent of speech codes, diversity workshops, and other forms of higher regulation. Some might attribute this to the greater mixing of the sexes in the office, but I believe a more basic reason is that when there is no concrete task that rules the job—an autonomous good that is visible to all—then there is no secure basis for social relations. Maintaining consensus and preempting conflict become the focus of management, and as a result everyone feels they have to walk on eggshells. Where no appeal to a carpenter’s level is possible, sensitivity training becomes necessary.
