DENBIGHSHIRE County Council has warned that there will likely be a 'significant reduction' in teaching staff when national strikes take place.
Parents and carers are being reminded that strike action by members of the National Education Union (NEU) is planned to take place on both Wednesday, February 1 and February 14.
DCC says this 'may impact' on the operation of schools within the county.
Additional strike days are also planned on March 15 and 16 and all of this, the council say, is 'anticipated to result in a significant reduction' in staffing levels within schools and will affect all areas of Wales.

A spokesperson for the council said: "All schools are currently assessing whether they can remain open or partially open on these days and if not whether the sites will need to be closed to learners on these days.
"Schools will communicate directly with parents and carers regarding individual decisions and information."
In addition, the National Association of Headteachers has notified Denbighshire Council that their members will commence action short of strike action as of February 1.
The spokesperson added: "Alternative arrangements may need to be put in place during these days should your school close or partially close."
