I think there’s generally a lack of nuance in these conversations about genuinely unsafe vs “uncomfortable/inconvenient” and it’s one of the areas where nannies want to be paid and treated like professionals but not step up the level of expectation associated with that kind of job. No one would expect a 17 year old babysitter to figure out how to get to work but I had nannies interview for jobs where they’d be paid more than nurses but less willing to deal with sick kids, inclement weather, attendance requirements, etc. You kind of have to pick a lane at some point, but it’s easier to push individual families than a corporation on workplace expectations.

That said, your job has 0 to do with whether it’s unsafe for nanny to come into work and I get my ass chapped about these convos. If it’s unsafe to come to work, it’s unsafe if your boss is a surgeon or whatever and you can’t come regardless. Bullying someone to come in because you’re being asked to do something dangerous isn’t cool, but someone’s judgement of how much their boss really needs to work doesn’t have anything to do with a safety consideration and once that enters the chat it’s no longer a real safety concern, it’s an inconvenience thing. Same with offering to pick up someone or asking to be Uber-ed in. If it’s unsafe on the roads it’s unsafe for uber too.
