戒告

1. Origins, structure, and basic meaning

• Structure: 戒告 is read as かいこく and is a noun and する verb for an official warning or reprimand issued over wrongdoing or a rule violation.
• Basic usage: Use 戒告処分を受ける for the disciplinary measure and 作業員を戒告する for the act of reprimanding someone.

2. Common pitfalls and similar expressions

• Difference from an ordinary warning
  • It carries more institutional or disciplinary weight than 注意 or a casual verbal warning and may be a formal disciplinary measure.
• Recipient and issuer
  • The disciplined person 処分を受ける, while a supervisor or institution takes the person as object in 人を戒告する.
