<human>: Give me the gist of the text in a nutshell

First off, I'm not quite sure of the best way to describe my situation while maintaining anonymity.  I will do my best to give as much info as possible and answer any questions I can while maintaining my privacy.

I am working 65-70+ hours/week in upper-level, salary management in the food service industry.  I understand that sometimes this is required but it has become the norm and it is completely unsustainable, physically and psychologically.  Right now, I am finding that to meet my budget for labor cost, I am having to do the work of 2-3 hourly people.  My employees are efficient and more than eager to do the work I have given them -- so this is not necessarily the root issue.  My budget does not seem to be *obviously* unrealistic.  I do have 1-3 new administrative/management tasks assigned each week.  These tasks, as well as communication, are not as streamlined as they could be.  

My organization is going through a leadership crisis -- growing quickly without **great** management candidates.  I have consistently blown expectations out of the water and I am not opposed to doing the work.  I would, however, like to be compensated for the time, sweat, blood, tears, and stress.  Either that, or I would like to have my budget adjusted to allow for either another management trainee or employee to whom I can delegate some of these tasks.  I am not sure how to approach my organization about this issue I am reaching a critical point and need help.  I want to frame the issue as a business problem -- because, well, it is.  I am trying to take classes and I would like to get to the gym a few times a week.  With the way things are now, this is not possible.

Help, Reddit!  Has anyone experienced this?  How did you deal?  Were you successful in bringing the problem to the attention of the organization?  What solutions can I offer when I present the problem?

If you have any questions, just ask and I will do my best to answer.
