I don't mind splitting if I'm getting a good contract, but if I have a crappy contract because I'm new, then I don't expect to have to pay 50% to get help in the field. So if you're at an 80% contract for life and you're splitting 50/50 with your manager that comes along, that means you're really only getting 40% from the work you're doing. That's a high price to be paying for training. Not to mention that usually you're using their closing skills, but the "behind the scenes" work is done by the new agent.
