It is a job which can leave crews drained, exhausted, and which can impact on their mental health.

But the importance of having a crew mate with a positive attitude has been highlighted at the East of England Ambulance Trust (EEAST) with a sing-a-long video posted to social media.

The video, which shows crew mates Rachel Harrold and Alexis Davis singing along to S Club 7's Reach in the front of their ambulance at the end of a shift, was posted on Twitter by operations manager Rob Adams who said: 'Some say morale is an issue. Not in this EEAST ambulance!'

Rachel, a newly qualified paramedic who has been with the trust for four years and qualified around a year ago, said: 'Me and Lexi had two shifts together and on the first day we had been signing along and we put loads of older music on.

'Lexi's full of energy, she has great positive energy so at the end of the shift the day before we did a video, we were driving back to base after a long 12-hour day and it made us both feel really good.'

Alexis, 22, an intermediate ambulance practitioner from Norwich, said: 'Our job is really good and every day is different but it can be stressful and has it's ups and downs. But it's what you make of it, and it makes a massive difference working with someone you can have fun with.'

Rachel, 26 and also from Norwich, said they posted the first one to social media and colleagues found it hilarious.

So on their second shift together they decided to post another.

Rachel said due to the job they did, where often they were faced with stressful, sad, and negative situations, it was important to have a crew mate who could cheer you up and keep spirits high.

She said: 'Quite a lot of the time it's quite negative when you're driving to a job because you're looking at what you're going to be dealing with but actually when I worked with Lexi there was no negativity. Even on the day we made that video in the morning we were called to a woman in her 80s and it made a difference to the care we gave to her, we were singing right up to the front door, we were bouncing around.

'We did also go to a sad job in the afternoon where the patient did not make it, so it's important to pick yourself up after that.'

Rachel said the pair had got patients involved too, as a 95-year-old woman on Saturday asked for Andrew Lloyd Webber to be played on the way to hospital.

'So as we were driving to the hospital the little lady was singing to Phantom of the Opera! Her face lit up and it was so lovely because she was very reluctant to attend hospital.

'It makes a massive difference if you're working with someone you can get along with, especially for me as a newly qualified paramedic I'm quite nervous in my new role but it helps to have someone so supportive.'
