To understand an employee's perception of the breastfeeding-friendly policies in the workplace, participants responded to the following questions: “What kind of lactation room was available in your workplace (independent space/without dedicated space)?,” “Were you aware of the pumping break policy (yes/no)?,” “Did you ever use the pumping break policy after returning to work (yes/no)?,” and “Did you feel embarrassed if you used breast pumping breaks (yes/no)?” Moreover, to assess employees' perception of workplace breastfeeding support, participants were asked, “After returning to work, did your colleagues, supervisor, and environmental health nurses encourage you to use breast pumping breaks (yes/no)?”
