Hi teachers,<br/><br/>Would you please help me use them? I have seen these a lot. But I can understand them.<br/><br/>Eve is not happy <b>in</b> her job. <br/><br/>Eve must work hard <b>at</b> her job if she is to be successful.<br/><br/>Eve always does exercise <b>at</b> her job during lunch break.<br/><br/>1. What's the difference between "in her job" and "at her job" in the sentences above?<br/><br/>2. Does "at her job" mean "at the office"? <br/><br/>3. I hear people say "happy with something". Can you say "Eve is not happy with her job"? <br/><br/>4. Is it natural to say: Eve is not happy with her job in the company? or Eve is not happy with job at the company<br/><br/>Thank you.<br/><br/>Tinanam
