Actually, English majors --those who can actually write--find employment. As one can tell by reading what we put up here, good writers are rare.
I have a couple good quality technical writers. They are employed on high priority projects from day one. What is special about these people is the capacity to grasp the subject matter and interact with the architects and designers. They often contribute great ideas while doing the critical job of capturing all the important ideas. Making them part of the project team from the start ensures they completely grasp the concepts and are prepared to express them accurately.
