Absent any specific issues you'd like to address, I'll make an attempt to answer the original question.
There are two relevant stories from Chinese history. One tale is about the governor of a large province, who ignores a hundred-man street brawl while touring the capital city. But he gets out of his carriage to ask why a farmer's horse is tired. When challenged by his advisors, the governor replies that local police do law enforcement, but it's his job to make sure that the harvest feeds everyone next year. If a horse is this tired in the Spring, it might be too hot.
Another tale discusses a time when the emperor had two prime ministers. He asked the younger one many questions that couldn't practically be answered, like how many swords were issued to the troops or how much water was in the reservoir. When posed with the same questions, the older minister responded that it was his job to advise and delegate, but not to know every detail of the nation's business. By way of example, he asked if it was his job to know the whereabouts of every thief and prostitute in the country.
The lesson here is that you need to know what your job is. If you're asked to do things that are beyond your responsibility, you must speak up and raise an objection respectfully. If you're asked to do more than you are able, then you must point out that you need help. If a manager doesn't know the amount of work that goes into accomplishing a goal, it's partly because the subordinates don't realize it's also their job to communicate that. It's not their job to know every detail of yours, but it is your job to give them feedback in a way that they understand. Unfortunately, that usually happens in a passive way that doesn't convey the information until it's too late.
