shirk

This term carries a strong negative connotation of laziness, cowardice, or a lack of integrity. It describes a deliberate evasion of obligation, often implying that the person is deceptive or opportunistic in their avoidance. While similar to avoiding a task, this word specifically targets the moral or professional failure of neglecting a duty. It is frequently used in workplace or military contexts to describe someone who lets others carry their share of the burden.
