AITA for nagging @ my hubs to defend me?

I posted in the comment section but for context. My husband and coworker are the only two automotive technicians at their job. Coworker has a history of trying to be competitive. So hubby and I did our best to make sure that our baby would be in separate times from their baby so that it doesn’t effect the business. My dad owns this business. So it’s in our interest to help my dad out so he isn’t without his two techs. Coworker knows this. CW specifically asked for our dd. Then he specifically asked for that date. CW admitted this - we are not assuming. When it was scheduled, he went to hubby and said that he purposely wouldn’t tell what day they scheduled on so we couldn’t modify our plans.
