Emergency call handlers are set to join a BT Group walkout later this week.
Around 500 emergency call handlers are set to walk out for the first time on Thursday as they join their colleagues. Further walkouts are planned to take place on Monday October 10, Thursday October 20 and Monday October 24.
The strikes are set to include the 30,000 Openreach engineers and 10,000 BT call centre workers who have taken action in previous months in opposition to BT Group management's offer of a flat-rate pay rise of £1,500.
