The agency has announced that proposed redundancies have been suspended while the flooding crisis continues.
The GMB union hit out at "successive years of central government cuts that have trimmed maintenance budgets to unsustainable levels."
The Environment Agency's Toby Willison said the organisation had faced "huge challenges" as a result of the floods.
"The planned reductions in posts will not affect the Environment Agency's ability to respond to flooding incidents and the Environment Agency will minimise the impact on other front line services through the changes" he added.
GMB official Paul Maloney said that a planned protest has been organised "because last week's EA announcement that consultation on redundancies has been put on hold is a sham".
This meeting shows that the EA is pressing on with the 1,700 redundancies as soon as the floods have receded. Management wants the meeting to discuss how the delay in consultation impacts on the timetable for job losses.
This is a ludicrous state of affairs - have government learned nothing from the current floods?
At the root of the current flooding crisis are successive years of central government cuts that have trimmed maintenance budgets to unsustainable levels.
What we need to see now is a clear commitment from Government to stop the redundancy process and to take the job cuts off the table.
