How to say "working" in Japanese

• 運転うんてんJLPT N4approx.Common
  noun, suru verb, transitive verb, intransitive verbCovers 'working' for machines and vehicles—the sense of running or being operated, as with an engine in use. It does not cover people holding jobs.
  現在げんざい５０台だいの機械きかいが運転中うんてんちゅうです。↗

  Fifty of the machines are running at the present time.
• 就労しゅうろうCommon
  noun, suru verb, intransitive verbCovers 'working' as being employed or hired—the state of having a job rather than the activity of doing it. Typical context: official statements about a person's employment status.
  ストライキとは従業員じゅうぎょういんの集団しゅうだんが一体いったいとなって就労しゅうろうを拒否きょひすることです。↗

  A strike is a mass refusal to work by a body of employees.
• ワーキングCommon
  nounThe English loanword. It turns up chiefly inside borrowed set phrases rather than standing alone, so for saying that someone works or a machine runs it is seldom the word you want.
• 採掘さいくつJLPT N1approx.Common
  noun, suru verb, transitive verbFits 'working' only in the mining sense: digging and extracting minerals from a mine. Unless the sentence is literally about working a mine, this is not the word you want.
• 在勤ざいきんCommon
  noun, suru verb, intransitive verbCovers 'working (in, at, for)': being employed at or holding a post with some organization. It states where someone works, as in a written profile, rather than the work itself.
  大阪おおさか支店してんに在勤ざいきん中ちゅうにはいろいろお世話せわになりました。↗

  Thank you very much for everything while working for the Osaka branch.

Match the sense: 運転 for a machine or vehicle running, 就労 for being employed, 在勤 for where or for whom one works, 採掘 for mining, and 「ワーキング」 only within borrowed phrases.
