"all employees should understand the personal consequences to them of having our tax rates increase dramatically if President Obama is re-elected, forcing taxpayers to fund President Obama's future deficits and social programs (including Obamacare), which require bigger government."

Statute 12.07 (3) No employer or agent of an employer may distribute to any employee printed matter containing any threat, notice or information that if a particular ticket of a political party or organization or candidate is elected or any referendum question is adopted or rejected, work in the employer's place or establishment will cease, in whole or in part, or the place or establishment will be closed, or the salaries or wages of the employees will be reduced, or other threats intended to influence the political opinions or actions of the employees.

Jed Lewison wrote a piece today about Mike White, the CEO of Rite-Hite industries, and his threat to his employees Turns out Wisconsin, which has a history of being a pretty progressive state, has a law on the books against that sort of thing.(Emphasis mine)

The question now is will the Republican Attorney General, J.B. Van Hollen, do his job and prosecute this CEO for violating the law? I am not holding my breath on it...

From Occams Hatchet in the comments - more of the e-mail that makes the threat very clear:

The other big impact on Rite-Hite employees, if President Obama is re--elected, is the good chance of losing Rite-Hite insurance and being put into Obamacare. Employers have the choice (though competition in the marketplace will dictate), to continue their existing plans or to pay a penalty and have employees go into the Government Plan. Our plan costs much more per family than the penalty and hence the possible competitive need to drop the Rite-Hite Health Plan. Every opportunity to make up for lost profits to taxes will have to be evaluated.
