Its a wise decision, especially seeing that no individuals 'private property' right is being violated.
What's 'private' about a parking lot?
There is no explicit or implied loss of constitutional rights just because you incorporate your business, your private property.
Nor do employees lose rights just because of your fears of what might happen on your private property.
The corportation maintains and provides a parking lot on their corporate property [for employee use] . That is private property.
Yep, private property which is not misused by locked cars which contain guns.
The employee probably signed an employment contract, of somekind, stating no guns on the private property.
Coerced, - void contract, - as you cannot be forced to 'sign away' an inalienable right.
Oklahoma has a Bill of Rights Article prohibiting the interfernce in the obligations of contracts.
And in this instance they are doing the right thing for employees who are not obliged to honor coerced contracts which infringe on their RKBA's.
Don't we want our government to protect our property rights and our contracts?
Yes of course. -- Why do you want companies that ban guns?
If you did not want guns on your home property and any individual drove into your driveway with a gun in their car or on their hip, as a private property owner, do you not have the right to ask them either remove the guns from your property or themselves from your property?
A company parking lot is not "your home property".
Sure, an individual at home has that right, but why would I want to disarm invited employees or guests?
On my property, I determine what rights will be exerted.
Be careful about shooting that armed trespasser, -- you might be convicted of a murder.
Their is a stronger constitutional case for the right to bear arms in court room than on private property. A court room is public property.
There is a strong constitutional case for the right to bear arms on all property. To my mind, searching everyone for pocket knives is a gross violation of privacy & our RKBA's.
