Actually, Jr. Steward food prep work is Cook work. Just because Stewards and Scullery Hands assist with it does not mean it isn't a cook function. If the justification for keeping Stewards around is food, then it's the wrong answer, because the CAF has a trade for that.
The Snr. Steward jobs with NPF are in the realm of finance, and unrelated to food prep... So why do we have an occupation that bounces from food prep/cleaning officers spaces, to finance? Does that seem like a wise use of limited billets in the CAF?
Could some of the RCNs retention issues be related to the way it treats it's people? Maybe sticking with 19th century ideas about how officers are served contributes to a toxic environment for Jr. pers?
@Halifax Tar already explained why you're wrong about the way it was communicated, so I won't belabor that point.
Lastly, you are correct in assessing that the RCN/CAF have been bad at making occupational changes, but you're ignoring that the changes happened because the old system was unsustainable. Keeping an occupation dedicated to serving officers is unsustainable, it needs to change. Other avenues were tried to keep the occupation relevant, but those have failed.
Occupations die, it's part of the CAF evolving to meet the needs of the times. I suspect in the next 10-20 years my occupation will die off, or be absorbed into another one.
