Apologies, I may not have been clear enough. I’m aware you have to do your Sunday if it can’t be covered.
Where I work, it’s usually very easy for a Sunday to be covered. Personally speaking, if I were a G9, the basic salary plus overtime and Sundays would make me less inclined to pick up overtime/ Sundays. I’d value my RDs a lot more due to the increased workload fatigue etc. I was wondering if this was reflected in ROCs etc. My OP was more of an anecdotal question rather than one regarding the official guidelines.
