Dear Muhammad,

Many thanks for taking part in our forum.
You see, many English words have similar meanings but in a certain context only one particular word is correct. Such is the case with the sentence you are referring to: Here we talk about a person's job - her contract with her employer. In this context the word job is more concrete than the word work describing a number of responsibilities and benefits.

As to your question on how to learn the proper use of English words - it's best when you try to memorize words in combination with other words, that is, you learn phrases (collocations, idioms, expressions etc.) instead of single words.
Please, let me know what you think.
Regards
Torsten
