Where I live, when you start a job for the first 3 months you are on a "probation period" where you can be fired without explanation. After the 3 months, they need to provide a reason. To the OP, are you saying that where you live, someone can be fired without explanation even after being at a job for over 3 months? If so, I would also disagree with that policy and feel like an explanation should be given after the probation period.
