You don't have someone sign a non-compete, you have them sign and agree to a Business Code of Ethics, or Business Policy. In this document, you can put whatever you want. Here are some exerpts from the one I use:
Excellent attendance is an expectation of all employees of ~~~~. Daily attendance is especially important for hourly wage employees whose customers and co-workers have the expectation of on-time attendance. Absenteeism is understood to be anything ranging from tardiness for a shift to completely missing a shift.
Absenteeism may be excused for extenuating circumstances, including major acute illness and the death of a family member or relative. The final decision regarding absenteeism rests with the general manager. An appeal may be made to the President, in writing by way of letter or e-mail, should an employee disagree with a decision made by the general manager.
Failure to notify a supervisor or manager of absenteeism will result in a verbal and written warning. Disciplinary action, up to and including employment termination will follow on any subsequent absenteeism that is not excused. Should the absenteeism result in the non-operation of business functions by the company (ex: missing the only shift that opens the business on a Saturday morning), the general manager or President may choose to supersede a verbal and written warning and immediately terminate the offending employee’s employment.
Employees will have access to company computer systems.
Employees are to refrain from the following prohibited activities:
- Accessing personal social networking web sites (ex: Facebook, MySpace, Twitter, etc).
- Accessing YouTube, Break.com and other video streaming web sites.
- Accessing personal e-mail.
- Accessing any pornographic material.
- Accessing any material deemed illegal by law, including but not limited to, Warez, hacking, virus distribution, copyrighted audio, etc.
- Accessing any material not directly related to the employee’s job function.
Any employee deemed to be in breach of the company Computer policy will be disciplined, ranging from a written letter of reprimand, to immediate dismissal. The general manager, solely, has the right to deem whether an employee is in breach of the company Computer policy. An appeal may be made to the President, in writing by way of letter or e-mail, should an employee disagree with a decision made by the general manager.
