Interesting. People come here as refugees ....
In the posts beneath this article there is a long post stating that the non-Muslim workers were forced to cover the Muslim's jobs during this sunset break, so worked 4 to 5 hours without relief so the Muslims would pray. There was an attempt to fix this and it led to this situation of conflict.
Interestingly, the article also says only the sunset prayer time cannot be shifted -- I wonder if this is only during Ramadan. There's another thread in this forum in which I posted an answer from the About.com's Islam Guide and she said the prayer times were flexible, but prayers had to be made up in the proper order.
My opinion is that if your religion restricts your work, you need to get a job that accommodates your religion.
