No, employers should not be allowed to prevent Muslim women from wearing burkas. People in the U.S. enjoy a constitutional right to practice their religions. This includes the right to wear the clothing that signals their beliefs. Allowing employers to make such rules simply violates a person's constitutional rights based on their membership in a class that is protected under Title VII of the Civil Rights Act of 1964.
No, employers should not be allowed to prevent muslim women from wearing a burka. It would be against the first amendment and an act of discrimination. There is no reason that women shouldn't be allowed to wear their burka while working. Religious articles of clothing have no impact on the quality of work.
It is not okay to force your opinion onto someone else. These women are not wearing burkas as a fashion statement, it is a part of their religious expression. If an employer stops an employee from wearing a burka it is called discrimination and may lead to a lawsuit, so it would be prudent to be accepting.
No, employers should not be allowed to prevent muslim women from wearing a burka to work. The United States Constitution guarantees its citizens religious freedom, which includes any garments that are worn as part of a religious practice. While that only applies to citizens, the United States has a history of being a place for all to avoid religious persecution, so the right of religious freedom should be afforded to all within our borders in all situations, including work.
