“We have about 1,600 people in BT/Openreach in Northern Ireland and we expect the majority of them to be on strike,” CWU NI Regional Secretary Erin Massey said.
“We were on strike before, but as part of that agreement the 999 emergency handlers were not on strike.
“We have to show the company we are serious.
“It is not an easy decision for us to make, for the emergency call handlers to go on strike, but the company has given us no other choice.
“They are ignoring our demands to come to the table.”
