Long time lurker but just to say I have represented many, many nurses and midwives in front of the NMC fitness to practise panels. You can absolutely work while you are under investigation. Some registrants have interim conditions imposed, some are on interim suspensions, many continue to work with no restrictions at all. Investigations can take years to conclude and there are hundreds ongoing at any given time so if everyone under investigation was forbidden from working you’d find the country short of nurses and midwives pretty quickly. It is entirely dependent on the investigation and whether a panel decides there is a need to impose conditions for public protection or to uphold the reputation of the profession. So unless you are representing MOD yourself no one here has any idea whether she is under investigation by the NMC or not and the register won’t tell you either. All the register will tell you is if there is an interim order in place and, as explained above, if there isn’t that still doesn’t mean there is no investigation.
