Pennsylvania employment law regarding election interference

I assume that most (all?) states have laws against threats, intimidation, and coercion to compel voting a certain way in an election. Pennsylvania has just such a law, 25 Pa. Cons. Stat. Ann. § 3547. But, did you know that it also has employer-specific provisions?

The following are misdemeanors:

• [B]eing an employer, pays his employes the salary or wages due in “pay envelopes” upon which or in which there is written or printed any political motto, device, statement or argument containing threats, express or implied, intended or calculated to influence the political opinions or actions of such employes, or 
• [W]ithin ninety days of any election or primary puts or otherwise exhibits in the establishment or place where his employes are engaged in labor, any handbill or placard containing any threat, notice, or information that if any particular ticket or candidate is elected or defeated work in his place or establishment will cease, in whole or in part, his establishment be closed up, or the wages of his employes reduced, or 
• [O]ther threats, express or implied, intended or calculated to influence the political opinions or actions of his employes.

Happy election day!
