1.
sidelined employees; employees left with no real work
employees who are assigned to desk positions near the window with little or no work, often as a way to push them toward resignation without firing them directly
窓際族になった。
I became a sidelined employee.
Cultural note
The word dates from the late 1970s. Because dismissing regular employees was difficult under long-term employment, some companies moved unwanted staff, often older ones, to desks by the window (窓際), away from the center of the office, and gave them little work in the hope that they would leave. The practice is less common now, but the word is still widely understood and is used half-jokingly of anyone sidelined at work.
