Grammar with possessive plural

Question

How do you write "the clients (plural) needs? Is it the clients' needs?

Example sentence: "I utilized interpersonal skills to identify the clients' needs." Is this sentence correct?

Answer 1

I utilized interpersonal skills to identify the clients' needs

Yes, this is grammatically correct. You put the apostrophe after the word in plural (i.e. clients) to indicate possession:

To show plural possession, simply put an apostrophe after the s.

Correct: guys' night out (guy + s + apostrophe)

Incorrect: guy's night out (implies only one guy)

Correct: two actresses' roles (actress + es + apostrophe)

Incorrect: two actress's roles
