When would you capitalize "Management", if ever?

Contracts, policy manuals, and rules often use defined terms.

See: http://lexicontools.com/defined_term.php

From that:

The standard convention in legal documents is to define terms in double quotes and designate subsequent references with initial capital letters.

Management is likely a defined term. Capitalizing defined terms is common practice in my experience.

EDIT:

Here is an agreement between the University of New Mexico and staff in which Management is a defined and caplitalized term-

For fun, here is an agreement in which State is a defined and capitalized term- http://www.irle.berkeley.edu/library/pdf/0112.pdf

And here is a contract in which the defined terms are in ALL CAPS and BOLD- http://www.irle.berkeley.edu/library/pdf/0356.pdf

I think that Management as a proper noun ie. as in the management team / the name of a department in a company would be capitalised eg. "have you asked Management about this?" or in a title of a book

However I think the concept of management ie. management of people/ managing people would not be capitalised.
