Questions(6)

What does 'work on' mean in a standup?
'Work on' means to spend time and effort on a task. In standups, engineers say 'I'm working on...' to explain their current focus. It's the most common way to describe what you're doing.
Can I say 'I'm working in' instead of 'I'm working on'?
No, use 'work on' for tasks and projects. 'Work in' describes your field or location (e.g., 'I work in fintech' or 'I work in Berlin'). For tasks, always use 'work on'.
How do I say I've been doing something for a while?
Use present perfect continuous: 'I've been working on this bug since Monday.' This shows the task started in the past and is still ongoing.
Is 'work on' too casual for formal emails?
'Work on' is neutral and works everywhere—standups, Slack, tickets, and emails. It's professional enough for any workplace context.
What's the difference between 'work on' and 'tackle'?
'Work on' is neutral and describes ongoing effort. 'Tackle' suggests the task is difficult or challenging. Use 'tackle' when you want to emphasize that something is hard.
How do I ask someone what they're doing?
Ask 'What are you working on?' This is friendly and natural. You can also ask 'What are you working on this sprint?' to ask about their current priorities.
