Boards placed on the gates of St Xavier's School in Nerul on Tuesday announced that all 300 teachers were on an indefinite strike.
As 100 parents supported the teachers, the school remained shut for the day.
The teachers claimed that since June they have been demanding payment in accordance with the Sixth Pay Commission recommendations, to no avail.
According to the education department, a school can pay its teachers as per the Sixth Pay Commission if the parents agree to pay the increased fees that would come into effect.
“The parents are willing to pay the hiked fees, but the management is turning a deaf ear," said Pratima Sharma, who has been teaching classes 9 and 10 at the school for the last two decades. “We don’t want the children to suffer but we have teach them to fight for their rights.”
The All India Federation of Parent-Teachers' Association secretary Ashok Kumar Pandey said they are ready to pay the hiked fee amount. "I do not understand why the hesitation with the implementation."
Supporting the strike, Surekha Sawant, a parent, said, “Nobody takes such a drastic step unless the problem is very serious.”
Vidya Salvi, who teaches classes 9 and 10, said: “There has been no communication from the management. We had asked Varsha Bhogle, one of the trustees, to talk to us, but she did not turn up.”
But Bhogale said: “We never said that we would not implement the Sixth Pay Commission recommendations. In fact we are trying to implement them as soon as possible.”
Principal Manisha Andhansare said: “We have been trying to contact the management but they have not given a positive response yet. In fact, a case has been lodged regarding the authenticity of the trust.”
A case has been filed against the trustees regarding misappropriation of funds.
But Bhogle refused comment. “There are several school and management-related issues pending in court. As the matters are sub-judice, I cannot comment.”
Some officials from the education department met the teachers, but they were not satisfied with the assurances.
“We intend to continue with the strike,” said Sharma.
