Irish schools do not have established substitute panels. I’m not sure how common this is, but it would make a lot of sense of they were to be established. Since the online claims system (OLCS) has been set up, there must be a huge amount of data to establish how many absences per day are in each area.
It would make a lot of sense to establish a panel of substitutes for clusters of areas where substitutes would be on call everyday and they would be paid as a full time teacher. The condition of employment would be that if the was work available, they would have to take it.
Obviously there would be days where more subs are needed than others but an average across the board would do the trick. For days where a sub isn’t needed, the person on the panel might be given a random school to work from and could be used to give a teaching principal a bonus admin day!
