One problem I see, aside from the difference in pay, is the part where the RPCD are guaranteed 40 hpw only if work is available (paragraph 1), but the 22.4 are guaranteed 40 without regard to work availability (paragraph 5). It does say in paragraph 4 that no RPCD will be displaced from classification or laid off if a 22.4 is working in the building. This seems to be a potential contradiction or paradox in the language.
