Science & Technology Executive Roles

Notice how in Seek and other web-based job advertisement facilities, there are Jobs, and then there are Executive Roles and the sub-categories for Jobs include Manufacturing, Transport and Logistics, Accounting, HR, Administration, Science and Technology, etc., yet in Executive Roles, there is no category for Science & Technology, yet there are categories for Administration and HR, for example.  Is it that organisations aren’t offering Executive Roles in Science & Technology, or is it that once in that salary bracket, the role is no longer considered to be in the field of Science & Technology?  What is this saying about science in Australia, or even globally?  Do we still wonder why people aren’t attracted to Science & Technology fields, or do we take it for granted that to avoid being monetarily disadvantaged, one must leave the field of Science and Technology?
