whatever が一般名詞の前にあるとき、それは形容詞です。ご質問の文では、coffee mugs を修飾している形容詞です。
whatever
= any ... that
= all ... that
Give me whatever money you have.
Give me any money that you have.
Give me all money that you have.
同じように、ご質問の文を書き換えます。
Employees are reminded to return any coffee mugs that remain on their desks to the cafeteria.
Employees are reminded to return all coffee mugs that remain on their desks to the cafeteria.
