The teachers' strike

Teachers who are taking part in the current strike are asking the gorvernment for the payment of the money they owed the teachers since 1981, teacher have been asking for the money for several years so far but the Chilean state has not showed any attempt to reach an agreement with teachers.
Accroding to my point of view this strike is completely fair because the money owed by the Chilean state is something they have to pay, they reached a sort of agreement with teachers 28 years ago, that it is why I think this is totally fair.
If somebody asks me if this is ethical, I would answer "yes, it is", in this case the government has not showed to deal with this situation ethicaly.
Although students are the most affected people with this unpleasant situation because most of them could fail in their attempts to succeed in their academic year.

Now the future is uncertain because it seems hard to reach an agreement because the government refuses to solve this problem and they only say bad things about teachers and everybody thinks the same. But the only thing I must believe in is that teachers are great.
