He is very lazy. I have never seen him working.
He is very lazy. I have never seen him work.
Are both of them grammatically correct? What is the difference in meaning between them?
I read the duplicate question, but I couldn't understand which one is correct in the above context. work or working?
I think work is correct, because it follows the verb tense in the first clause.
I think working is useful in another context. when the situation is temporary e.g.
It seem he is frustrating, I haven't seen him working recently.
