ED seems to have suspended SP for ED's benefit, to stop upsetting incidents for ED - like having to manage people, in her role as a manager.
TBF in a small hospital where there will probably be loads of people who have worked there for decades, and a regular influx of newer younger staff, it wouldn't be surprising if some staff were sick to the back teeth of each other for all kinds of reasons. But as an example, hypothetically, if Sandie had been bringing a love for Trump to work in a disruptive way, it'd be unlikely to be new. The Trump era has gone on a long time,and she's entitled to her beliefs. If any kind of discussion disrupts core business, ED has had a long time to take advice and deal with disruption. Or to learn how to shut her ears and let things go that are not a manager's business to comment on. ED is trying hard to throw shade but just seems to be showing herself up as a totally incompetent people manager in all of this.
And I say all this as a lefty liberal who would be driven bonkers listening to anyone's politics at work whatever position, but defend absolutely their right to vote how they want and go on holiday wherever they bloody choose.
