I found the following post in the Star Tribune interesting. Some Muslims working as cashiers in a supermarket are refusing to touch (wrapped) pork products, instead asking the customers or another cashier to scan them and put them into the bags.
I remember a few years ago a local Rabbi was asked for a psak about a teenage who wanted to work in the snack counter of a local theater that served hot dogs with cheese and other basar b'chalav combinations. He suggested she not take the job.
The sources quoted in the article seem to think that the cashiers' actions are legal, and that this falls within the requirement to 'reasonably accommodate' the religious beliefs of employees. Initially I thought this was unacceptable, but after more thought I'm inclined to agree.
