your body's union rep, demanding rest before management runs the whole machine into the ground

means A state of physical or mental exhaustion that builds up from exertion, stress, or overwork and demands recovery before you can function well again.

from From French 'fatigue,' from the verb 'fatiguer' (to tire), descending from Latin 'fatigare,' meaning to weary or wear out. The military sense — 'fatigues' as in dull, tiring chores, and the plain work-clothes soldiers wore to do them — grew naturally from the same root, since few things wear a person down like endless drudgery.
