Every hard-working synonym praises a slightly different habit: diligent is careful and steady, dedicated is loyal to a cause, industrious is busy and productive, and tireless never seems to stop. Committed sits close to dedicated and suits teams and long projects.
Because the phrase is so common on resumes, recruiters skim past it. So each section here offers another word for hard working that fits a real setting, plus casual nouns, spelling notes and the antonyms. More job vocabulary waits in resume and work words.

From keen to assiduous
Each chip in the top strip trades a little warmth for polish. Keen is friendly and especially British; it means eager and ready to put effort in. Dedicated is the safe middle and works almost anywhere. Diligent adds care and suits teachers' comments and performance reviews. Industrious feels a little old-fashioned but still reads well in references. Assiduous is formal and precise, best in academic or official prose.
For sheer strength, tireless and indefatigable go furthest. Use them for someone whose effort truly stands out, or they will sound like flattery.

A reference letter draft: "Tom is hard-working." A hiring manager learns little from that. "Tom is diligent: he double-checks every invoice and has not missed a deadline in two years" turns the label into proof.
On resumes, show the effort instead of claiming it. A result with a number does more than any adjective.
Hard working, hardworking or hard-working
All three spellings appear. Before a noun, use the hyphen or the closed form: a hard-working crew, a hardworking crew. After a verb, many writers drop the hyphen: the crew is hard working. The noun phrase is hard work, and its swaps include effort, diligence and graft. For the quality itself, the dedication synonyms page has commitment and devotion.
Casual words for a hard worker
In speech, people often use a noun instead. A go-getter chases opportunities. A workhorse carries a heavy load without fuss. A grafter is British slang for someone who works hard with their hands or on long shifts. An eager beaver is keen, sometimes a bit too keen. A self-starter needs no push, so recruiters print it in so many listings. Keep these for chat, team shout-outs and informal notes.
Swaps that change the meaning
Busy only means someone has a lot to do, not that they do it well. Ambitious is about wanting success. Workaholic suggests an unhealthy habit and can sound critical. Obsessive is negative in most contexts. Proactive means acting early, which is valuable but different from putting in long effort.
The opposite of hard working
Lazy is the everyday antonym, and idle is a softer, older one. Indolent is formal. Slack and careless point to poor effort on a task. Work shy is British and blunt.
- He was idle all summer.
- The report was slack in places.
