If you can refuse the on-call agreement and still keep your job, then it is okay. Otherwise, it is an option for employers to take away their employees' free time as they wish. The cost of my time as an employee is not linear. Just because I am selling 8 hours of my time for X money, doesn't meant I would be happy to sell 16 hours for 2X money. And if I am taking a week of a vacation, it means I want to relax and walk somewhere in nature and be left alone. If you want someone available 365 days a year, hire two people.
