The kanji 労 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is a part of 木 (ki), which can represent "wood" or "tree" and is used here for sound. The right side is 力 (chikara), meaning "power" or "strength." Thus, the original meaning was related to physical labor, as suggested by the combination of "wood" and "strength." The character evolved over time to encompass various concepts related to work, effort, and hardship.
