The figures come during another week of industrial action over NHS pay that started on Monday with strike action by midwives and other NHS staff.
During the week of strike and further industrial action by NHS staff in early October, RCM members claimed for overtime they would normally work for free.
They recorded their overtime on timecards provided by the RCM. With almost 500 responses and more still coming in, the results show that midwives worked an average of three hours overtime during that week.
Just 13 hours overtime – or just over four weeks for most midwives – is equivalent to each midwife receiving the very modest 1% pay award recommended by the NHS Pay Review Body. This recommendation was rejected by the government and NHS employers.
Cathy Warwick, chief executive of the RCM, said: “We want a settlement to this dispute as do other health unions. It is affordable and it is needed because investing in NHS staff is ultimately an investment in better care.
“Our support on the picket lines shows that our members and other unions are prepared to stand up and continue to fight. The government and NHS employers need to know that this is not going to go away.”
The overtime statistics follow a poll of public opinion by ComRes for the RCM on the 1% pay award. This showed that the public remains overwhelmingly in favour of the increase for NHS staff.
Midwife and maternity support worker members of the RCM will be claiming for overtime again during further industrial action this week.
