Grenville gives little opportunity for advancement (at least in my setting) either in the work you do or the pay you make. Supervisors continually pass requests back and forth not wanting to commit to any one answer, afraid of making a decision.
It feels like you have come to a "Stop", a wall rather than an open road in your career. Much more suited to a young first or second job type person.
Can't think of one beyond "A pay cheque"
