Re: sentence usage
Someone in authority will stop something from happening.
I don't work directly with "Anne," but she works in our company. She told me that she was going to send product A to a customer, but I know that product A should not be shipped out because there is a problem with it. I tell Anne this. She says, "Look, my orders were to ship it out today. No one told me about any problems, but I know that I'll have a problem with my boss if I don't do what she said to do--ship this out today."
I try to convince Anne to hold the shipment. She insists she will have it on the FedEx truck by 4 pm. I call my boss to intervene.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
