The Tertiary Education Union says more than 800 of its members at polytechnics are preparing to go on strike next week over their pay and conditions.
The Union's says members at six polytechnics have voted in favour of taking industrial action over proposals that include increasing teaching days and raising salaries by 1%.
National industrial officer Irena Brorens says the TEU has written to the polytechnics with a counter offer. However, members are prepared to strike if the negotiations are not settled by Monday.
The six polytechnics involved in the negotiations are NorthTec, Bay of Plenty, Waikato Institute of Technology, the Western Institute of Technology, Whitereia and Unitec.
