My point is if a employee has this installed on their own device on their own then its on them. If its required by a employer then that person gets a alert they were exposed then where does that liability fall for the park? Does the park then have to pay to get the person tested, does the park not let that person work? Does the park provide health insurance to cover the cost of testing and does the employee have sick leave to still get paid while out waiting for the test to return.
I think the park would be walking a fine line requiring all employes have the app and have it working. Also does the park have a policy about sell phone use? I think any employer mandating the use of the app is wrong unless they are using a company supplied device or recieve a stippend for the device. Im not saying the app is bad just that when employers get involved things could get complicated.
