English tenses are the heartbeat of communication. They show when something happens and help listeners or readers understand the flow of time in a sentence. But if you’ve ever paused mid-conversation wondering whether to say “I worked,” “I was working,” or “I have been working,” you’re not alone. These phrases look similar, yet they each reveal a slightly different layer of meaning about time, duration, and action.
When you say “I worked,” you’re talking about something that’s finished — an action completed in the past.
When you say “I was working,” you’re describing something that was happening for a period of time in the past.
And when you say “I have been working,” you’re linking the past and present — describing an action that started before now and may still be happening.
Understanding these distinctions isn’t just grammar for grammar’s sake. It’s about expressing yourself clearly. The right tense can help you tell stories more vividly, sound more fluent, and even write more professionally.
The Basics of English Verb Tenses
Tenses show time. But they do more than tell us when something happened — they also show how long and whether the action is still happening. Let’s start with a quick overview.
| Tense | Example | Focus | Time Reference |
| Simple Past | I worked | A completed action | A specific point in the past |
| Past Continuous | I was working | An ongoing past action | Ongoing or interrupted past |
| Present Perfect Continuous | I have been working | An action started in the past and continues | Past → Present |
English has twelve main tenses, but these three — simple past, past continuous, and present perfect continuous — are among the most useful for everyday speech and writing.
Each one paints a different picture:
- Simple Past gives a snapshot of a finished event.
- Past Continuous stretches that snapshot into a short video — something happening over time.
- Present Perfect Continuous connects that video to the present moment.
Let’s explore each one closely.
Understanding “I Worked” – Simple Past Tense
Definition
The simple past tense describes a completed action that happened at a specific time in the past. It doesn’t continue into the present — it’s done, finished, and no longer happening.
“I worked” means that your work is over. The job or activity took place at a certain time before now.
Structure
Subject + past form of verb
Examples
- I worked
- You danced
- She played
- They studied
The past form of regular verbs ends with -ed, while irregular verbs have unique forms (e.g., go → went, eat → ate).
Usage Examples
- “I worked at a café last summer.”
- “She worked hard and got promoted.”
- “They worked on the project yesterday.”
Each of these actions has a clear ending in the past.
When to Use “I Worked”
Use the simple past when:
- The time of action is known: I worked at Google in 2020.
- The action is complete and not connected to the present: I worked out this morning.
- You’re telling a story or narrating past events: I worked all night, then finally fell asleep.
Common Mistakes
- ❌ I worked here for five years.
(If you still work there, use “I have been working.”) - ✅ I worked here for five years before I moved.
Tip: Always link “I worked” with a finished time frame — yesterday, last week, two years ago, in 2015.
Understanding “I Was Working” – Past Continuous Tense
Definition
The past continuous tense (also called the past progressive) describes an action that was happening at a certain time in the past. It often sets the scene for another action or event.
“I was working” means you were in the middle of an activity at some point in the past.
Structure
Subject + was/were + verb-ing
Examples:
- I was working
- He was reading
- They were sleeping
Usage Examples
- “I was working when you called.”
- “They were watching a movie at 9 p.m.”
- “She was studying while it was raining.”
These sentences describe ongoing actions that were interrupted or happening simultaneously.
When to Use “I Was Working”
Use this tense when:
- You want to emphasize duration or ongoing activity:
I was working all afternoon. - You want to describe background actions:
The kids were playing while I was working. - You’re telling a story and setting context:
I was working late when the lights went out.
Common Mistakes
- ❌ I was worked there last year.
(Wrong form — don’t use “was” + past tense together.) - ✅ I was working there last year.
Tip: The past continuous is dynamic — it adds life to your storytelling and helps your listener imagine the situation.
Understanding “I Have Been Working” – Present Perfect Continuous Tense
Definition
The present perfect continuous tense connects the past and the present. It describes actions that started in the past and continue now, or that have recently stopped but still affect the present.
“I have been working” suggests you started working before now and are still working — or just finished recently.
Structure
Subject + have/has been + verb-ing
Examples:
- I have been working
- She has been studying
- They have been waiting
Usage Examples
- “I have been working here for five years.”
- “She has been practicing all morning.”
- “They have been waiting for you since 8 a.m.”
These actions have duration and continuity.
When to Use “I Have Been Working”
Use this tense when:
- The action began in the past and is still ongoing.
I have been working at this company since 2019. - You want to emphasize how long something has been happening.
I have been working for hours — I need a break! - You want to describe recent, unfinished activities.
I have been working on that report; I’ll finish soon.
Common Mistakes
- ❌ I have been work for three hours.
(Missing –ing form.) - ✅ I have been working for three hours.
Remember: Pair this tense with for and since
- For + period of time → for two days, for five years
- Since + starting point → since Monday, since 2018
Key Differences Between the Three Tenses
To truly master them, you need to compare their meanings side by side.
| Expression | Tense | Time Focus | Example | Use Case |
| I worked | Simple Past | Completed action | I worked last night. | Past action (finished) |
| I was working | Past Continuous | Ongoing action at a past time | I was working when it rained. | Interrupted or background action |
| I have been working | Present Perfect Continuous | Ongoing from past to now | I have been working since 9 a.m. | Continuous or recent activity |
Timeline Visualization
Past Present
|————|—————-|
I worked → Finished action
I was working → In progress in the past
I have been working → Started in past, still going
Real-Life Examples and Contextual Usage
Let’s apply these tenses in realistic scenarios.
1. Talking About Job
- I worked at a law firm before I became a teacher. (Completed job in the past.)
- I was working as a designer when I met my husband. (Ongoing at a specific past time.)
- I have been working remotely since 2020. (Still happening now.)
2. In Daily Conversations
- “Sorry I didn’t answer — I was working.”
- “I worked out this morning, so I’m exhausted.”
- “I have been working nonstop lately; I really need rest.”
3. In Professional Settings
During interviews:
“I have been working in digital marketing for six years.”
“I was working on a big campaign when I got promoted.”
“I worked for three major companies before starting my own.”
Notice how the tense changes what the listener understands about time and experience.
Common Errors Learners Make
Even advanced learners mix these up. Here are the biggest pitfalls:
| Mistake | Explanation | Correction |
| I worked here for five years (still working). | Simple past implies it’s finished. | I have been working here for five years. |
| I was working every day last week (regular activity). | Past continuous isn’t for habits. | I worked every day last week. |
| I have been working yesterday. | Can’t use present perfect with a past time expression. | I was working yesterday. |
Quick Tip
“I worked” = Finished
“I was working” = In progress
“I have been working” = Continuing or recently active

Tips for Mastering These Tenses
- Listen and notice: Watch English shows or podcasts and note when speakers say was working or have been working.
- Use timelines: Draw time lines to visualize start and end points.
- Practice storytelling: Mix all three tenses to describe events naturally.
- Focus on time expressions:
- Yesterday, last week → Simple Past
- At that moment → Past Continuous
- For, since, lately → Present Perfect Continuous
- Keep a tense journal: Write one paragraph each day using different tenses.
Case Study: Maria’s Job Story
“I worked at a bakery for two years after college,” Maria said. “While I was working there, I learned how to manage a team. I have been working in food service ever since.
This short story uses all three tenses perfectly. The first shows a completed job, the second describes ongoing experience in the past, and the third connects past learning to her present career.
