Forms
窓 (window) + 際 (edge, beside) → beside the window
Second meaning
The second sense comes from the expression 窓際族 (literally "window-side tribe"), referring to employees who have been given no meaningful work and spend their days sitting by the window with nothing to do. This is a uniquely Japanese corporate phenomenon where companies don't easily fire employees, but instead marginalize them.
