The compound adjective "work-related" is a modern formation built from two core English elements. The first element, "work," has a deep Germanic origin, tracing back to Proto-Germanic werkan and ultimately to the Proto-Indo-European root werg-, meaning "to do." The second element, "related," originates from Latin, entering English via the verb "relate," which carries the sense of establishing a connection or link. The logic of the compound is transparent and literal: it directly describes something that is connected to or associated with one's work or job, a concept that became particularly salient with the rise of industrial and office-based employment structures.

Structure: work (noun) + related (adjective) - work: From Old English 'weorc', meaning "something done, action, proceeding, business, military fortification." In this compound, it functions as a noun denoting employment or labor. - related: From the past participle of the verb 'relate', itself from Latin 'relatus', the past participle of 'referre' meaning "to bring back, report." In this compound, it functions as an adjective-forming suffix meaning "connected to."
