oh, and even if you’re working in secular place: i know of someone who worked in a completely secular hospital in a totally secular city, but during pesach the guards would ask everyone as they would enter if they have chametz in their bags.
I worked in a place in Kfar Saba where the admin assistant went through the kitchen before Pesach, cleaned everything, kashered the oven, put the toasters away, etc., then covered the counters and table. Afterwards, she put up signs about not bringing in any outside food over Pesach, and sent out emails saying the same thing. This was in a place where there were only two outwardly dati people, although many were “traditional” sfardim.
Maybe I’ve been lucky, but I’ve worked (and live) in some great places where people are generally tolerant of those who are not like them between the dati’im and those who are secular.
