Title

Aside from knowing how to ask about someone's job and knowing how to say what your job is, you are still tasked with learning occupation-related terminology from various angles in order to assimilate in a Japanese work environment. 

To streamline the learning process, we'll be learning key terminology via charts organized by theme. Each chart will be followed with example sentences that thematically build off the words shown. 

Word Notes:
1. 「で働く」vs 「に勤める」: When working at a company as a full-time position, ～に勤める is used. When referring to just working at a job, ～で働く is used.
2. 退社 can both mean "to leave one's company of work after completing one's tasks" as well as "to quit/resign" said company. Although it may seem confusion would arise often because of this, the latter meaning is typically qualified with a time phrase as a matter of business etiquette. It is highly unlikely that this word is used in total isolation because of how it could be interpreted either way otherwise. 退勤 and 退職 may be used to avoid ambiguity, but practical use, 退社 is still incredibly common. 

3. 帰社する is sometimes confused with 退社する even by native speakers, but it actually means "to return to one's company of work." This expression is not all that common in the spoken language due to being homophonous with 貴社, which is an honorific term used to refer to another person's company. 
4. 貴社 and 御社 are both honorific words used to refer to another person's company, but the former is more prominent in the written language, whereas the latter is more prominent in the spoken language. Similarly, 当社 refers to one's place of work, but when you wish to speak of said more humbly. you would use 弊社. 

10.  部長は部門や部署の責任者で、最終的な意思決定を担うことも多い役職だ。

15.  従業員を雇う場合には、給与支払や社会保険加入の手続きなど必要になる公的な手続きがいくつかあります。
When hiring an employee, there are several procedures regarding public affairs such as wage payment and social security enrollment that are necessary.

Word Note: 給料 and 給与 both mean "pay/wage," but the latter includes any and all compensation for work, whereas 給料 only refers to monetary earnings.

33. この間、バイト先に給料を受け取りに行ってきました。店長に、「給料取りに来ました」と言ったところ、「給料を取りに来たんじゃなくて、貰いに来たでしょ？」というようなことを言われました。働く人がいなければ店は回らないので、そんな下手に出る必要はないと思うのです。働いたその瞬間からお金を受け取る権利はあるとして、月末まで待つのだからその分は店が私に借金していると考えてもいいと思っています。
The other day, I went to my part-time job to get my check. When I asked my store manager, "I came to get my check," I was corrected with, "don't you mean you came to 'receive' your check?" If there were no workers, the store wouldn't run, so I don't think going down to that level is necessary. I think that provided you have right to receive money the moment you've worked, since you're waiting till the end of the month, the store is in debt to you. 

Word Notes: 

1. In slightly dated Japanese, 看護士 and 看護婦 were preferred to refer to male and female nurses respectively, but nowadays, 看護師 is used to refer to nurses indiscriminately of biological sex.

Many occupations are directly tied to an expertise and/or field of research. Of course, several kinds of occupations may handle the same kind of expertise. 

Word Notes:
1. 医師 implies that the doctor meets the legal criteria to perform medicine. Meaning, that individual has an 医師免許証 (doctor's license). In everyday speech, however, it is 医者 that is primarily used to refer to someone who treats people.

Just from the handfuls of occupation titles that have been showcased thus far, it is apparent that there are several suffixes used to indicate said doers. Of those suffixes, perhaps the ones most confused with each other are ～者 and～家. Whenever it is possible to use either suffix, it is generally the case that the latter indicates a professional, whereas the former indicates someone that happens to do said task or is at least the go-to form when professional status is not pertinent. 

Word Note:
1. At first glance, 研究者 and 研究家 seem to break the norm mentioned above. Typically, 研究者 is the go-to word for "researcher," whereas 研究家 refers to someone who "professes to research/be a student of" some study. Or, more specifically, a 研究者 is viewed as someone who is affiliated with a research institution and is salaried, whereas a 研究家 is not necessarily subsisting off said expertise, but they are seriously invested in it. So, say if you are a recently hired 研究者, you may not have the findings to back being called a 研究家.

Some of the most prestigious jobs in society are held by experts (専門家) in specific fields of study (研究分野), and as we saw earlier, the suffix ～学 meaning "the study of," is fundamental in creating those sort of terms. The fields of study, or subjects, listed below are more attuned to research positions, also serving to showcase the sort of things you might study in schooling. 

For the words showcased below, the way to turn the field of study into the person who conducts that study is adding the suffix ～者 after the suffix ～学. 

Word Notes:
1. Due to 科学 (science) and 化学 (chemistry) being homophonous, many speakers choose to colloquially pronounce the later as ばけがく to distinguish them in the spoken language.
2. In the context of university, there are two words that translate to "to major/specialize in": ～を専攻する and ～専門にする. The former is used to refer to what you are primarily studying in, and once you've gotten your degree and you wish to describe what you expertise is, you use the latter.
