Situational

Imagine a contractor tells you a lighting upgrade is going to take twice as long as planned. What do you do next?

how they handle vendor coordination problems and whether they escalate appropriately rather than freeze

If you noticed a safety or compliance issue while walking through a facility area, but it wasn't part of your assigned task, what would you do?
