Indeed. The other point that I was going to make is that these incidents can encourage people to leave their profession, because they are so distressed and every day is a dark reminder of the ordeal that they have been through. That is dreadful, because we need our emergency workers. If we continue to lose them because of these incidents, it will only lead to further shortages of people who play an invaluable role in society. Time is also lost when emergency workers are in hospital or when they take respite leave after an incident. Attacks on police officers between 2016 and 2017 were estimated to have caused six days of lost time on average.
Assaults on emergency workers also create an additional cost for the taxpayer. The annual estimated cost to the NHS of healthcare-related violence is £69 million, which is equivalent to the salary of 4,500 nurses. We could do a lot more with this money. A survey by the Royal College of Nursing found that 47% of its members who had been physically assaulted would not recommend a nursing career. That is the last thing we need when we are looking to recruit more nurses and doctors. A survey of violence against frontline NHS staff reported that 2% of workers a year in England hand in their notice or change their job because they have been physically assaulted.
I congratulate the Bill Committee on its work and the amendments it made, which broadened the scope of who is considered to be an emergency worker. I am delighted by that, because for too long we have forgotten or overlooked people who are on the frontline and are serving to protect and assist us every day. The provisions will now cover prison escort services and those working on the NHS frontline, and staff and volunteers will protected by the Bill if assaulted while providing a service under contract from the NHS. As we have heard, the Bill will also cover those who are working off duty but are performing their roles. A firefighter is still a firefighter if they are assisting in a fire but not actually doing their day job.
We owe a debt of gratitude and respect to our emergency workers for the courage, commitment and dedication that they demonstrate in carrying out their duties. I am proud to support the Bill and amendment 3. Together, they will ensure that we stand up for those who stand up and protect us.
