Title VII of the Civil Rights Act of 1964 is a federal law that
protects individuals from any discrimination based on
religion.
Employers can't discriminate against religious beliefs and can
not refuse to hire anyone on the basis of their religious
practices.
Employers also have to take care of religion of their employees
while making job decisions.
Religion sometimes requires that the employee have to behave
particularly like wearing specified items , hair styles and
clothing at work and employer can not discriminate against
this.
If religious belief conflicts with employment requirement, the
law requires employer to find a solution and accomodate employee
belief.
Employers can not restrict religious expression of
employees.
