The Teachers' Union of Ireland is calling for resources to tackle the teacher recruitment and retention crisis in the budget.

It wants to see an increase in teaching allocations to schools at second-level, allowing for the recruitment of teachers on a full-time basis.

A recent survey has shown only 31 per cent received a full-time contract with their first job.

TUI President Liz Farrell says schools and students will struggle if things don't change quickly.
