There will be minimal supervision at public schools while up to 400 western Sydney teachers attend a two-hour stopwork meeting at Rooty Hill RSL at 9am.

Teachers will tune into a Sky Channel broadcast where they will hear from NSW Teachers Federation officers about its dispute with the Government about salaries and new staffing agreements enforced at the start of term two.

Members will vote on the next stage of industrial action.

Since a protest last May, teachers from Rooty Hill High, Lethbridge Park and Tregear public schools have emailed and faxed their concerns to the Government and Department of Education and Training (DET).

They fear it will become harder to attract qualified teachers to work in the St Marys/Mt Druitt area, after the DET abolished a priority transfer points system which enticed teachers to disadvantaged areas such as western Sydney. NSW Teachers Federation organiser Henry Rajendra expected 21,000 teachers to attend today's stopwork meetings.

``Teachers in western Sydney call for the Premier to immediately enter into meaningful and genuine negotiations and avoid further industrial disputation and disruption,'' he said.

``They are bitterly angry and are determined to take on the Government in defence of their students and their industrial rights.''

Mr Rajendra said that it's up to the Government to resolve the dispute.

``The Teachers Federation has written twice to the Premier, on July 7 and 14,'' he said.

``The letters requested a meeting to peacefully resolve the current dispute about teacher transfers. The Premier has yet to respond.''
