The Teachers' Union of Ireland (TUI) has said the issue of performance-related pay should have "no place" in the new round of benchmarking negotiations and that benchmarking should be entirely separate from general pay increases.
In an editorial in the latest issue of the union's newsletter, TUI News, union president Paddy Healy also calls for comparisons to be made with "well paid" private sector employment when calculating rates of pay.
The TUI's annual conference takes place next week in Dublin.
"We are opposed to additional work being imposed on teachers in return for benchmarking payments," Mr Healy writes. "We want the comparison made at a snapshot in time."
In a wide-ranging article, he also criticises a recent OECD report which suggested that teachers should be offered ongoing contracts instead of permanent jobs. Teachers' right to a sworn public inquiry and ministerial assent in advance of dismissal is also being called into question, he warns.
"During the past year senior officials speaking on behalf of the previous minister have told the union that the Government does not regard existing teachers as being unconditionally permanent," he claims. "This is completely unacceptable to the TUI."
However, a spokeswoman for the Department of Education said this related to the community and comprehensive sector.
Unlike in other sectors, no scheme currently exists for the redeployment of teachers if, for example, a school closes. Talks on such a scheme should take place at the teachers' conciliation council, she added.
