Why yammer?
Yammer is a place for employees to let off steam and for mis-managers to identify trouble makers. Why post there?
We should be hitting the CHP with demands for science based procedures and the CAD with safety issues (FTLs - rest periods / white chairs).
If you are worried about being sacked for raising legitimate safety concerns, use the TOR browser and anonymous email services. Copy the media in. Public shaming of dumb government policies. This is something the AOA should be all over, perhaps they are scared of the NSL and CCP.
