This month the DOL has a public comment period on a 160 page rule change and tucked into that new rule is a section that will require staffing agencies to file with the government when they supply temp workers to businesses experiencing strikes, walkouts, or slow downs initiated by unions.
The new rule seems to also require that the people these temp agencies hire to also file their names and addresses with the DOL via a new form they would have to fill out. (See Labor Union Report for a copy of the form in question and for more technical info on this rule.)
These forms will be public knowledge as soon as the government gets its hands on them. That means that workers’ names and home addresses will also be public knowledge. That means that union thugs can get hold of these names and addresses so that they can amass lists of workers to scare away from their job in order to save union jobs.
