Because they want to please the public, I’m thinkin’. 

Workers at the Tyson Foods poultry processing plant in Shelbyville will no longer have a paid day off on Labor Day but will instead be granted the Muslim holiday Eid al-Fitr.

According to a news release from the Retail, Wholesale and Department Store Union, a new five-year contract at the plant included the change to accommodate Muslim workers at the plant.

The majority of the workers at that plant are Muslims so I guess that’s ok.  On the other hand Labor Day has become US tradition, something that should be respected as well.
