Frequently Asked Questions

What is the difference between personal and personnel?
Personal is an adjective meaning belonging to or affecting a particular person, or private: “personal belongings,” “a personal matter.” Personnel is a noun meaning the employees or workforce of an organisation: “all personnel,” “the personnel department.” Personal is about the individual; personnel is about the group of employees.
What does the personnel department do?
The personnel department manages a company’s workforce: hiring, firing, contracts, training, pay, and employee welfare. It is now more commonly called the Human Resources (HR) department. “Personnel” in this context is used as an adjective modifying “department,” “manager,” “records,” etc.
Is “personal manager” the same as “personnel manager”?
No, and this is a common error. A personnel manager manages the HR/staffing function of an organisation. A “personal manager” would mean a manager assigned to you personally — which is a very unusual concept in most workplaces. In professional writing, if you mean the HR or staffing manager, always write “personnel manager.”
Is personnel singular or plural?
Personnel is interesting grammatically. As a noun referring to a group of employees, it can take a plural verb: “The personnel are trained.” As a collective noun referring to the workforce as a unit, it can take a singular verb: “The personnel department is on the third floor.” Both are used, but plural is more common in British English when referring to people.
Can personal be used as a noun?
Personal is almost always used as an adjective. However, in journalism and advertising, “a personal” (noun) can mean a personal advertisement: “She placed a personal in the local paper.” This is informal and context-specific. In all other uses, personal is an adjective.
What are common collocations with personal?
Common collocations: personal belongings/possessions, personal data/details, personal life/space, personal opinion/view, personal trainer, personal statement, personal development, personal relationship, personal assistant (PA), personal best (PB in sport). Note: personal data is a key term in GDPR and data protection law.
What are common collocations with personnel?
Common collocations: all personnel, key/senior personnel, military personnel, medical personnel, personnel department/manager/records, qualified/trained personnel. Personnel is common in formal, military, corporate, and official contexts.
How do you pronounce personal and personnel?
Personal is stressed on the first syllable: PER-son-al. Personnel is stressed on the last syllable: per-son-NEL (rhymes with “hotel”). The different stress is a helpful audio clue: if the stress is at the end (-NEL), you are talking about employees.
What is “personal data” and why does it matter?
Personal data refers to any information that can identify an individual: name, address, email, phone number, biometric data. Under GDPR in Europe and the UK, personal data must be handled carefully and with consent. “Personal data” is a legal and technical term distinct from “personnel records” (employment records kept by an organisation about its staff).
Is personnel always used for large organisations?
No. Personnel can refer to the staff of any organisation, large or small. “The cafe’s personnel” or “military personnel” — both are correct uses. However, the word sounds more formal, so in casual contexts people tend to say “staff,” “employees,” or “workers” instead of “personnel.”
