Members of the Teachers' Union of Ireland have taken part in a series of lunchtime protests over pay discrimination. 

The protests did not affect student services and were held outside schools, colleges and Institutes of Technology where TUI members work. 

The union claims members who entered the profession since 2011 are paid less than colleagues who entered the profession before then, resulting in pay inequality. 

The TUI is calling for the issue to be addressed immediately and for the pay of newer members to the profession to be restored. 

The TUI also says the pay inequality issue is linked to low morale in staffrooms, to a collapse in applications for post-primary teacher training courses, and to a dramatic rise in emigration among post-primary teaching graduates. 

The union says recruitment difficulties have arisen in several subject areas as a result.
