I worked for the NHS for 16 years and we worked as a team. Your situatuation does not sound like teamwork, it sounds as though you are being very petty. If the colleague concerned worked overtime and assessed two patients and did not order the equipment required but did contact the manager to ensure the equipment was ordered for the patients, I cannot see what the problem is. She may have been feeling ill, perhaps the stores that hold the medical equipment was closed for the weekend so the paperwork would have been held up and possibly lost so she spoke directly to the manager to ensure that the patients got the equipment they needed. I applaud her for doing this.
I and another lady was in charge of assessing patients for their medical needs and we had a massive store that housed all medical equipment and if the equipment was urgently required, I would ensure that the patient got what they needed as quickly as possible, we covered for each other so no patient ever lost out.
I would hate to be working with you lot. I now know why the NHS is in such a mess because you are not prepared to help each other in support of patients.
Disgusting.
