Well, as always when a Govt. & top managers have lost trust of a public sector work-force, and fail to settle a long running industrial dispute, the next step is pretty much always the consideration of a ban on striking altogether.
So, you'll be unsurprised that NHS senior managers, after three years of on-off conflict with Resident Doctors, are asking Wes Streeting to consider a legal ban on strikes by doctors. Streeting has so far demurred but how much longer?
