Brothers, sisters, aunts, uncles or is it any relation?they are referring my complaint to the Member Relations team

Where do they get these department names from? What's wrong with 'Membership'? I know its not just CAMC, but I am sure someone sits in every company coming up with department and role names.
A company I worked for we had a restructuring exercise and they appointed me to a new role. Personnel, as it was then called before it became Human Resources, came up with a job title of 'Senior Manager - Business, Application, EPOS, Hosting and Technical Systems Support'!! I protested but they would not budge until they found it would not fit on the badge we had to wear if visiting a site! I suggested and they eventually agreed to Systems Manager - Support. (There was already a Systems Manager - Development so dropping the 'senior' was already a precedent. All other senior managers in the business wore the title).
Never worked out if these department titles and role names are just ego boosters. Couldn't believe when I worked with NCR how many 'Vice Presidents' and 'Assistant Vice Presidents' they had.
