It should be "its difficulty" (or "how difficult it is")

OK then! So just replace ''employee'' with ''person'' and that's it :)

I think they're saying they want (an employee?) to rank how hard they find certain tasks they come across throughout the day.

They're giving an example here: the employee might be required to get to the post office to send an important parcel or letter before it shuts at the end of the day, and that might be essential, but it's not exactly difficult [so the employee might think twice before ranking it as being 'hard'].

Sometimes it can start to seem like the whole world is crashing down. Work and school start piling up, house chores and responsibilities, commitments to friends and family—there just aren’t enough hours in some days. Learning to prioritize effectively can help you become a more efficient worker, saving time, energy, and stress. Learn to organize your tasks into distinct categories and levels of difficult, and start approaching them like a pro.
Steps:
1. Choose a time-frame for your list. Do you have a particularly busy week coming up? A crazy day? Maybe thinking about everything you need to do before the end of the year is driving you nuts. Whatever the nature of your commitments, select the time-frame of the priorities list you hope to create to help you start managing those priorities and translating that stress into meaningful action.
2. Rank the effort required for each task. It might be critical that you get something to post-office by the end of the day, but this isn’t a terrifically difficult task. Rank everything on your list in terms of its difficult so you’ll know how to situate it in relation to other tasks.
