When they are interviewing you, which do you think they'll ask?
- Do you tend to put the extra mile in when necessary?
- What have you done recently that involves going the extra mile, when necessary?
The first is something everyone will say yes to. Everyone. Who wants to be seen as someone who works 9-5, no matter the situation?
Likewise, any company will answer yes to "Does your organization value its employees?" Really. How awkward would that moment be when you ask me that and I say "no, never."
"What are things your organization has done recently to show how it values its employees?" is a perfectly valid question. The only people who will be uncomfortable with it are those who have no examples.
Do you want to work for those companies? If so, then asking the question is a little risky, yes. If not, then you're showing that you know you have options and that you're genuinely interested in taking the right job, not just any job.
