The claim from a teachers representative in the Premier County come as the three main teachers unions hold their annual conferences this week.
The ASTI says new teachers will earn around 100-thousand Euro less over their lifetime than senior colleagues, hired before 2011.
Regional representative for Tipperary Aidan O'Leary says having a well educated workforce is key to attracting new businesses to the county but education cuts in recent years will hamper this.
At their conference Primary school teachers have heard that cuts to newly qualified teachers were discriminatory, inequitable and unreasonable.
Around 850 delegates are attending the annual congress of the Irish National Teachers Organisation in Wexford.
General Secretary Sheila Nunan says the attacks on newly-qualified teachers were utterly unfair.
Meanwhile some teaching representatives claim new staff are being forced to leave jobs because they can’t afford to pay rent – with some earning less that 15,000 euro a year.
Aidan O'Leary – who teaches at the Presentation Secondary in Ballingarry – says teachers are now finding it almost impossible to buy a house because of their low wages.
