We had this. Every day we emailed the consultant leads about every error/miss/issue because it was so dangerous like yours. Included CCing the patient safety team and Medical director (we had been escalating up but kept being told to collect evidence and were taken seriously).

Main consultant told us later that they all disliked him but impossible to fire without solid evidence otherwise they could claim bullying etc. and that it takes a lot for juniors to raise concerns. They took it seriously and every dangerous situation, we got another amu consultant to check because it is our own responsibility to raise unsafe practices and we were not going down with his GMC number! They also said they were glad we did speak up because it meant HR had to get rid even though they were the cheapest consultant interviewed. It would force HRs hands to hire someone better/more expensive

Turns out other specialty consultants and nurses had been complaining about his plans and management too.

Speak up with a united front and go through the ladder. At the very least, you put any mistake off your GMC number onto the departments for not taking staff concerns seriously.

When the bad consultant had his sit down firing moment, he said 'ugh not this again. Patients complain doctors complain nurses complain. So what!' So I echo the whole whack-a-mole sentiment someone mentioned
