(名詞/不可數) 銹壞 － 一種極度疲累及缺乏熱情的感覺，這種感覺是由工作上步調緩慢、沒有足夠的事情可做或是由長時間都是做一些沒有成就感的工作所引起的。
引句：
The vast majority of us are familiar with the concept of burnout, especially those who work in fast-paced or high-pressure industries. But, according to experts, a lesser-known workplace phenomenon has now emerged: rust-out, burnout's bored, disengaged cousin. Rust-out is commonly caused by "moving too slow" or being "still for too long".
