I would change the sentences. They sound a little rough to me.Originally Posted by ntasan
1. He was not working for the NY times as a journalist.
2. He did not work for the NY times as a journalist.
Sentence number two can be followed by: (2) He was a photographer for the NY times.
Sentence number 1 can be followed by: (1) He was working as a photographer for the NY times.
Keep the 2 simple past sentences together and keep the 2 past progressive sentences together. I would use the sentences in the simple past. They sound better.
