It might...although in a case against the employer rather than the employee. Here's my thinking:srothstein wrote:Second, you can be forced to sign anything as a condition of employment. You can still refuse the consent to search since the SCOTUS has ruled many times that consent can be revoked at any time. You will be fired for refusing the consent at the time needed, but it can be done. If the search takes place after you refuse the consent (as some employers may be wont to do), the worst that can happen is you would be fired. The evidence would not stand up in court for any criminal case at all.
I'm assuming the OP locks his vehicle after parking it (especially if he leaves a firearm in it.) As such, any search of that vehicle after consent has been refused would involve breaking into it, as well as whatever locked container the OP keeps his gun in (assuming one of those as well.) I'm not able to find the applicable TX statutes (if any) so I don't know if the law allows employers to break into an employee's private vehicle, even if parked on company property...but I tend to doubt it. I could be wrong though.
