McD exec's speech interrupted by minimum-wage protestors
Protesters angry about McDonald's Corp. wages today disrupted a lunchtime speech given by Jeff Stratton, head of the company's U.S. operations, and demanded that he do something about restaurant worker pay. "Do you think it's fair I have to live on a poverty wage?" said Nancy Salgado, 26, who works at a McDonald's in Logan Square. The mother of two said she couldn't afford to buy her youngest child shoes after paying rent. Mr. Stratton apologized to the First Friday Club of Chicago guests, several from Old St. Patrick's Church, who filled the Union League Club's dining room as Ms. Salgado's tirade continued for roughly five minutes before she and others were escorted out.

The shutdown, the IRS and your taxes

If you were thinking that the government shutdown meant you would get out of paying your taxes, think again. While only 9% of Internal Revenue Service employees -- roughly 8,750 out of nearly 95,000 workers -- are currently working, the underlying tax law remains in effect. That means "all taxpayers should continue to meet their tax obligations," according to the IRS's website. Need an IRS employee to answer a question, though? "That's where there will be challenges," said Edward Karl, a certified public accountant and vice president of taxation for the American Institute of CPAs. Not only are customer service agents unavailable, but the Taxpayer Advocate Service, which fields consumer complaints, is also closed.

Cooper, Apollo at odds over merger terms
Cooper Tire & Rubber Co. is asking the Delaware Chancery Court in a complaint to compel India's Apollo Tyres Ltd. to "expeditiously close the pending" $2.5 billion merger of the two companies. Cooper in essence is accusing Apollo of attempting to renegotiate the firms' merger pact by "seeking to delay an agreement" with United Steelworkers Union locals at Cooper Tire plants in Texarkana, Ark., and Findlay, as ordered by an arbitrator on Sept. 13 after the USW sought arbitration, claiming Cooper's planned sale to India's Apollo Tyres Ltd. violates successorship provisions of the union's contracts with Cooper.

Gas prices plunged almost 14 cents in the past two weeks
The latest Lundberg Survey of 2,500 service stations says the price of a gallon of regular gasoline is down 20 cents in the past two weeks. Survey president Trilby Lundberg tells CNN that the average price of $3.39 is 45 cents lower than it was a year ago. Lundberg says the drop in the past two weeks is the biggest since November of last year. But she also says the recent delcines may have bottomed out. The lowest price was in St. Louis, where customers paid an average of $3.01 a gallon.
