Answer:
Step-by-step explanation:
There are several errors in the sentence "EMPLOYEE'S MUST WASH THEIR HANDS BEFORE RETURNING TO WORK."
1 Capitalization error: The word "EMPLOYEE'S" should be capitalized as "EMPLOYEES."
2 Possessive error: The word "EMPLOYEE'S" should not be in possessive form. It should be "EMPLOYEES" without the apostrophe.
3 Spelling error: The word "RETURNING" should be spelled as "RETURN."
4 Grammar error: The word "BEFORE" should be followed by a verb, such as "RETURNING." It should be written as "BEFORE RETURNING."
The correct sentence would be: "EMPLOYEES MUST WASH THEIR HANDS BEFORE RETURNING TO WORK."
