How are multiple personnel in department the only ones standing deck watches?

Dog weekend duty and Duty Section has 200+ Personnel,but personnel in our department are triple watched, double watched often. Most of deck watches are stood by us every duty day despite being a decent sized duty section.

Maybe we’re more undermanned than it seems?

Is this an accidentally oversight or full apathy?

What’s the right way about going about this without making baby tantrum adults blowing a gasket?

How come a lot of people treat this job like welfare instead of service?
