In Brazil the labor relations are heavily regulated. Each hour you are on-call you make 1&#x2F;3 of a regular hour of work, and while you answer a call and work on weekends or at night you are paid twice the regular hourly wage.<p>You are expected to answer the phone promptly, be sober and do anything to remedy the problem including reaching for other people that can fix it (does not have to be a permanent solution).
