The school teacher situation is quite interesting as in some ways the jobs are similar i.e it's a practical job and it doesn't matter how many degrees you have. If you can't teach you can't teach.
Does the degree act as a glass ceiling through which you cannot pass without one.
I wonder how many head masters and other teachers in senior positions do not have degrees?
This discussion of who can and who cannot call themselves an engineer reminds me of the issue surrounding the rank structure for the newly formed Royal Air Force in 1918.
Lord Trenchard wanted the title Marshall of the RAF for the top job.
The army objected as the title of marshall was only awarded to senior generals who had proved themselves.
Trenchard won his argument by pointing to the title of Provost Marshall.
Step 1 is to ensure that the title of "engineer" only applies to those with a degree.
Step 2 is to put pressure on EASA to have the title "engineer" written into the legislation.
Step 3 Remove certification rights from non "engineers".
It's all about money. If they can restrict positions to degree holders only
by law, that reduces competition for well paid jobs.
This might be called a hidden agenda except for the fact that it's so obvious.
