Loyalty implies the predecessors of:

•  having and then knowing what both of your real core values are and then 
• establishing where a particular task or relationship fits into your priorities"
• it fits both of our senses of calling - my purpose - what I am supposed to do.

Loyalty requires the element of mutual respect and love

If you haven't identified what your "center" is or should be

you don't have anything to base the question of whether or not you can be "Loyal"  to someone or something. 

I don't think you can be loyal if you have no defined "center".

From the perspective of Loyalty, my "center", my core values, begin with God, His economy - what my perception is regarding what He is doing on the earth.  My marriage and family come next and then my personal sense of calling - what I feel my personal mission is. 

I shouldn't commit to a relationship or a task until through prayer, fellowship, and consideration, I am clear about how it fits within my core values, and is within my calling.  If there are possible conflicts with my values, or calling, I should be open and genuine about these conflicts and fellowship them to a conclusion.

Loyalty has conditions 

• If at some future point the task or relationship in question is not longer congruent with your center you will not be loyal.  If someone is no longer loyal to you chances are either your center or their center has changed. 
• If we can no longer in good conscience remain loyal to a person or task, our sense of integrity should prompt us to fellowship this with the appropriate people and make a decision together on how to go on from here. 

Personal Considerations on Loyalty

• Loyalty is a goal. 
• I believe we (Diverse CTI) present a business model and culture that matches the core values of the people I want to attract.  The result, if we hire the right people,  should be loyalty.  If loyalty is lacking I believe there is a fundamental mismatch somewhere in an area that is more important than the matter of loyalty.  This is what needs to be discovered and addressed. 
• It isn't easy to detect disloyalty.  If someone has a true center of personal gain he isn't likely to come tell you he is now greedy and is about to steal from you.  He will hide his heart and his actions from you as best as he can.  If you have a funny feeling, consider looking deeper.
• We all have a fallen nature and could deviate from our core values if the right temptation came along.  So create checks and balances to make it very difficult for someone to be tempted.    Don't provide a carrot to tempt the fallen nature.
• Interview the spouse.  You will learn what the other side of the elephant looks like when you meet the spouse. 
• Put your employment agreement in writing and have the employee sign it.  It should include a job description and detail what and how they are paid.  Don't give anyone any ground to believe you have not lived up to your part of the bargain. 
• If you, the employer violate an agreement, don't ignore it and hope it will go away.  The employee is keeping score with employee math.  You get 10 demerits for every one of his.  Keep the slate clean.  You aren't perfect and neither is your employee. 
• Decisions are from the mind.  Loyalty is from the heart.
