I left my previous job because I didn't get along with my coworkers.
I didn't see eye to eye with my coworkers, so I decided to leave my job.
"I left my previous job because I didn't get along with my coworkers." is a simple and straight forward way to say you 'quit' (a more gentle word for this is 'left') your previous (last one) job because you and the people you worked with there made it difficult or you didn't like working with them.
"I didn't see eye to eye with my coworkers, so I decided to leave my job." uses a saying that is common in native English speakers - 'see eye to eye'. To see eye to eye with someone means you agree on things, see things in the same way. So to say that you didn't see eye to eye with your coworkers is a nice way to say that you simply didn't see things in the same way and ultimately, didn't get along. This is also a great way to make the statement that is gentle, non offensive to the people you are speaking about and doesn't place blame.
"I left my previous job because I didn't get along with my coworkers."（前の仕事は、人間関係がうまくいかなかったので辞めました）
は、シンプルでストレートな言い方です。「前の仕事は、人間関係がうまくいかなかったので辞めた」と伝えています。'left' は 'quit'（辞めた）のより遠回しな言い方です。
"I didn't see eye to eye with my coworkers, so I decided to leave my job."（同僚とそりが合わなかったので仕事を辞めることにしました）
ここでは、ネイティブスピーカーがよく使うイディオムが使われています、'see eye to eye'。
'see eye to eye with someone' は「意見が合う／考え方が一致する」という意味です。
ですから、'I didn't see eye to eye with my coworkers' で「職場の人と考え方が合わなかった［馬が合わなかった］」という意味になります。この表現を使うとすごく穏やかな言い方になります、人を責めていません。
I quit my last job because I didn't gel with my coworkers
