for one's trouble

for (all) one's trouble

In exchange for the effort that one has made. Usually, the "reward" that such effort yields is negative. A: "But you've been so much better about getting to work on time!" B: "Yep, and all I got for my trouble was the boss criticizing my typing skills instead." And what did I get for all my trouble? A lousy commemorative pin.
