American Metals:I have a small manufacturing plant in Baird, Texas about 20 employees. All management speaks english. Can I require that English be spoken. I think it would be a safety issue.
Job relatedness becomes the focal point of an English only policy. For instance, if you punish two guys for speaking in non-English while they're standing at urinals while a manager who happens to be seated in a stall overhears them, you could be in for a problem. Same for off-the-clock-but-on-the-premises discourse, for example, in the break room at lunch time.
Consider this: you could have a safety problem requiring a bilingual lead to explain a safety procedure in English to a non-native speaker of English (who shares a native tongue with the bilingual lead).
I haven't had to mess with this since 2000 but I wouldn't expect the job relatedness business to go away.
