This is major. Yes we all got into EMS to worry about medical issues but there is a lot more to the job. If your company relies on contracts and someone being a hot head threatens that contract, there will be no hesitation to send you packing. If there is an issue, let the supervisors/management approach it.I'd also take statements around demanding information carefully. Most transport crews (BLS, ALS, HEMS, or otherwise) are reliant on their contracts with hospitals, and worry about their image quite a bit. Arguing with ED or other staff is probably going to get you in trouble with your own company. If you really don't feel like you have enough information and the hospital staff are unable or unwilling to provide it then you should be contacting the supervisor on your service.
