15 Useful Idioms for Working Hard
1. Burn the Midnight Oil
Meaning: To work or study late into the night.
When to Use: Use this idiom when someone stays up late because they have work, studying, or an important deadline. It is common in informal and neutral English.
Example 1:
I had an exam the next morning, so I burned the midnight oil to finish my revision.
Example 2:
The design team burned the midnight oil to complete the project before Friday.
This idiom focuses on working late, not simply working hard during the day. It can also suggest that someone is sacrificing sleep to finish something.
2. Go the Extra Mile
Meaning: To make more effort than is normally expected.
When to Use: Use it when someone does more than the basic requirement. It works well in workplaces, customer service, education, and everyday situations.
Example 1:
Maria always goes the extra mile to help new employees understand their jobs.
Example 2:
Our teacher went the extra mile by giving us extra practice before the test.
The key idea is extra effort. You do not simply complete your duty; you do something more to help achieve a better result.
3. Put Your Nose to the Grindstone
Meaning: To work hard and continuously on something.
When to Use: Use this idiom when someone needs to stay focused and put serious effort into a task. It is usually informal or neutral.
Example 1:
If I want to finish this report today, I need to put my nose to the grindstone.
Example 2:
She put her nose to the grindstone and completed the course in six months.
The expression suggests steady, focused work. It is especially useful when talking about someone who stays with a difficult task instead of getting distracted.
4. Work Your Fingers to the Bone
Meaning: To work extremely hard.
When to Use: Use it to describe very hard or tiring work. It is common in informal speech and can sometimes suggest that the work is exhausting.
Example 1:
My parents worked their fingers to the bone to provide a good life for their children.
Example 2:
The restaurant staff worked their fingers to the bone during the holiday weekend.
This idiom is stronger than simply saying “work hard.” It emphasizes how much effort and energy someone uses.
5. Pull Your Weight
Meaning: To do your fair share of the work or responsibility.
When to Use: This idiom is useful when people are working as a team. It can be used positively or as a criticism when someone is not contributing enough.
Example 1:
Everyone on the team needs to pull their weight if we want to finish on time.
Example 2:
James always pulls his weight during group projects.
Be careful with the meaning. Pull your weight does not simply mean “work very hard.” It means contribute your fair share.
6. Put Your Shoulder to the Wheel
Meaning: To make a strong effort to accomplish something.
When to Use: Use it when talking about serious effort, especially when a difficult job needs everyone’s help.
Example 1:
We all need to put our shoulders to the wheel if we want to meet the deadline.

This idiom often works well when a person or group faces a challenging task. It highlights hard work and cooperation.

Example 1:
If you keep your nose to the grindstone, you should finish the assignment by tomorrow.
Example 2:
He kept his nose to the grindstone throughout the training program.
This expression is very close to “put your nose to the grindstone.” Both describe focused, serious work. The difference is mainly grammatical: put often describes starting or applying yourself, while keep emphasizes continuing that effort.
8. Work Like a Dog
Meaning: To work very hard.
When to Use: This is an informal idiom for strong effort. It is common in conversation but may sound too casual for formal business writing.
Example 1:
I worked like a dog all weekend to get the house ready for the guests.
Example 2:
She worked like a dog during her first year of business.
The expression is often used to emphasize intense or tiring work. It can be humorous, but it may also show that someone feels exhausted by their workload.
9. Move Heaven and Earth
Meaning: To do everything possible to achieve something.
When to Use: Use this idiom when a goal is very important and someone is willing to make a huge effort to reach it.
Example 1:
I will move heaven and earth to make sure my family gets home safely.
Example 2:
The organizers moved heaven and earth to make the event a success.
This idiom is stronger and more dramatic than “work hard.” It suggests making every possible effort, especially when something matters deeply.
10. Go All Out
Meaning: To use your maximum effort or energy.
When to Use: Use it for competitions, events, projects, performances, and other situations where someone gives everything they have.
Example 1:
The players went all out to win the final match.
Example 2:
We are going all out to make this year’s school festival special.
This is a common and flexible informal expression. It means giving your maximum effort, rather than doing something halfway.
11. Knuckle Down
Meaning: To begin working seriously and with concentration.
When to Use: Use this informal phrasal expression when someone needs to stop delaying or being distracted and start focusing on work.
Example 1:
I have wasted enough time. It is time to knuckle down and finish my assignment.
Example 2:
The students knuckled down before their final exams.
Knuckle down often suggests a change from being relaxed or distracted to becoming serious about a task. It is especially natural in everyday British and American English.
12. Slog Away
Meaning: To work hard for a long time, especially at a difficult or tiring task.
When to Use: Use this informal expression when the work feels long, repetitive, or demanding.
Example 1:
He slogged away at the report all afternoon.
Example 2:
They slogged away for months to build the new business.
Unlike “go the extra mile,” this idiom does not necessarily suggest enthusiasm. It often focuses on the effort and difficulty involved in continuing with demanding work.
13. Burn the Candle at Both Ends
Meaning: To work or live in a way that uses up your energy by staying up late and getting up early.
When to Use: Use this idiom when someone is doing too much and not getting enough rest. It often has a negative or warning tone.
Example 1:
You cannot burn the candle at both ends every week and expect to feel rested.
Example 2:
She had been burning the candle at both ends while studying and working part-time.
This idiom is related to working hard, but it is not usually praise. It often warns that someone is working too much and may become exhausted.
14. Give It Your All

Example 1:
You have trained for months, so give it your all in the final race.
Example 2:

This phrase is encouraging and positive. It focuses on maximum personal effort, even if success is not guaranteed.

Example 1:
The detectives promised to leave no stone unturned in their search for the missing evidence.
Example 2:
We will leave no stone unturned when looking for the best solution to this problem.
This idiom is not limited to physical work. It focuses on thorough effort and making sure that no possible option is ignored.
How to Use These Idioms Naturally
The best way to use idioms is to match them with the right situation and tone. Not every expression means exactly the same thing, even when several relate to hard work.
Use “burn the midnight oil” when the important point is working late. Use “go the extra mile” when someone does more than expected. If someone is simply making a lot of effort, “give it your all” or “go all out” may work better.
For teamwork, “pull your weight” is especially useful. It means doing your fair share, so do not use it simply as another way to say “work hard.”
Tone also matters. Expressions such as “work like a dog,” “slog away,” and “knuckle down” are informal. They can sound natural in conversations, blogs, stories, and friendly messages but may not be the best choice in a formal report.
Some idioms have a negative or cautionary sense. “Burn the candle at both ends” often warns that someone is working too much. It should not normally be used as praise.
Also, avoid forcing an idiom into every sentence. Native speakers use idioms naturally and selectively. If a simple phrase such as “She worked hard on the report” sounds better, use it.
Finally, remember that idioms should fit the subject. “Leave no stone unturned” is natural when discussing a detailed search, while “pull your weight” fits a team situation much better.
