[Are we speaking of Islamic indicators and not just Muslim attire?]

Read your List of disallowed organizations (might be federal only), though unfortunately, the federal government does not soft-classify Islam as problematic, (the List last-I-saw was only hard-problems): Certain ‘organizations’ -domestic or foreign- are banned business– You do not want to be in the same room, On the telephone-with, Etc.

The soft-problem with Islam is you do not want it harder by hiring:

Try think of it this way: Your daughter applies for work at a place that does money-laundering, taking-of-usury, tax-evasion, you don’t like because it’s bad business, because Islam forbids it, Whatever, But they hire her anyway because “she’s got religion”–and so–they corrupt your sweetie-pie-daughter in the ways of “The Bad Company:” they put her in accounting to record all their money-manipulations.

(Even the ‘filthy rich’ are require to work as corporate managers.)

What can we say–? Muslims don’t want to be mean about it–but–you should recognize that you don’t have easy freedom to hire a muslim: especially if your company borrows money from stockholders…banks.

(Used to be common in churches; a religious expression.)

Generally job Applicants would seem capable of avoiding wearing any ‘not-this-job’ identifier-tag articles: Business clothes are in, Trinkets are out (little-jewels may be in, big jewels may be out), doggy-do tees are…
