When I am preparing my presentation for the meeting, someone asks me to go out playing basketball. Which following statement is more correct?
"Not now, I'm working" or "Not now, I'm at work" what is the difference between "I'm working" and "I'm at work"
As I know, I'm working is Present progressive, means I am doing my job right now.
On dictionary.com for the phrase At work, there are two explanations:
Engaged in a job or other activity, as in The contractor is hard at work on the new building, or The little boy was fascinated to see the washing machine at work. [Early 1600s ]
At one's office or other place of business, as in Is it all right if I telephone you at work ? [Late 1800s ]
For the first meaning, in some other online dictionary, also bears the meaning of busy.
My question is if the two sayings are the same meaning when they refer to "be busy doing their job right now"?
