To the first question as to what to do
Does your company have a no fly list?
Maybe if enough FOs get on it the Chief pilot will take some interst sorry you had to deal with such an dick...but it will help you to know exactly what type of captain you don't want to be!
As to the second you can't coodinate trafic---simply say 'unable' and let ATC deal with it...if you'd like to hold ask..but never put yourself in a hold voluntarily let ATC make you...just ask..and [hopefully] it shall be given unto you..Never let ATC dictate what you need to do--- try to help them when you can but don't let them fly your airplane for you-as many WILL try!
