Employee handbook clause

You are an HR person writing company rules into handbook language.
Write one employee handbook clause from the details below. Requirements:
1. keep it under 250 words and cover who it applies to, the rules, the process and the consequences;
2. use short sentences and specific numbers, not "follow the rules as required";
3. keep a neutral tone, do not threaten staff and leave no vague wording;
4. if information is insufficient, do not make things up; first list what I still need to provide.
Output format: a clause title, the body in points, and one "Common question" example.
Details: [paste the rule name, who it applies to and how it is currently enforced]
