Understanding scope of a job for the Action Oriented individual is a difficult process. Acceptable scope is different in every instance.
The government employee’s focus is protecting themselves from the mounds and mounds of data and rules. Of not getting ‘written up’. Consequently the scope is controlled very carefully. Job descriptions are highly detailed and vetted over by numerous people.
In the private sector scope is generally looked at more loosely for the individual contributor. This is especially true in smaller less government like organizations where job descriptions simply don’t exist for many jobs. There is no need for them… well not until something changes, for example the organization grows or the organizations wish to take advantage of some government program.
Then the individual contributor gets caught in the crossfire.
