Both who and that can refer to people (someone who/that cares, people who/that work here, kids who/that like to read). Who is preferred in formal usage, such as academic writing.
Who and that as relative pronouns
Both who and that are, which link to the nouns they describe.

The pronoun “who” introduces a that describes “the architect.”

- We sell shoes that are environmentally friendly.
The pronoun “that” introduces a clause that describes the noun “shoes.”

- The new owner, who thinks he knows everything, has fired half the staff on his first day.
- This is the story of a woman who believed in herself.
- The man who wrote this book has won an award.

of people ( that refer to humans).

When to use that

Who vs. that for people
You can use both who and that to refer to people.
- I’m looking for someone who/that can work with wood.
- How can I contact the doctor who/that is treating me?
- The player who/that has the most tokens wins the game.
In formal writing, prefer to use who instead of that to refer to persons.
- More formal: We need someone who understands horses.
Less formal: We need someone that understand horses.
- More formal: Who is the reporter who asked this question?
Less formal: Who’s the reporter that asked this question?
Note that that can replace who (or) only in . (A restrictive clause is to identify the person or thing being referred to and is not .)
- Someone who/that likes challenges would love this job.
- Managers who/that have already replied should ignore this email.
Always use who instead of that to refer to a person in a nonrestrictive clause. (A nonrestrictive clause provides an optional description and is enclosed in commas.)
- Rita, who/
thatlikes challenges, wants to climb Mt. Everest.
- My manager, who/
thatunderstands software but not people, thinks I work because I like working.
Can that refer to a person? Additional guidance
Grammar and usage authorities generally agree that the pronoun that can refer to both people and things. Dictionaries (like Oxford, Merriam-Webster, and Cambridge) define the word that as a relative pronoun that can refer to people, animals, and inanimate objects.
Merriam Webster’s Dictionary of English Usage as well states that that refers to persons and things, providing examples from both earlier and current literature. Likewise, The Cambridge Grammar of English notes that the pronoun that can replace who and whom in a wide range of informal styles.
Given the preference for who over that in formal styles, it is not surprising that some style manuals, like the AP Stylebook and APA Publication Manual, recommend using who instead of that to refer to people. Others however, like the Chicago Manual of Style and MLA Handbook, note that both who and that can be used for people.
