Brewer Co, campaigned to recruit they got a response yes we will do it but on Kosher terms, they did have jewish volunteers but wasn't run with halacha in mind
When I was in yeshiva in Monsey (a few decades ago), I used to watch sports games in the fire station and got to know a few of the firefighters; a large portion of the firemen there were OTD (before that term was coined), or extremely modern orthodox. So I can understand why there's sensitivity around having a real kosher atmosphere - it certainly wasn't, at least at that point, a good place for a "heimish" person.
