First of all, if you are convicted, and maybe even if you aren't, the DBS might consider barring you, although common assault is not a "relevant offence", so unless it's for something that happened while you were working with vulnerable groups, barring won't be an option. They would offer you the chance to make representations, and Unlock can offer you information and advice about that
. The second point is that ex-offenders aren't necessarily vulnerable people in the strict sense of DBS barring. Unless your job is limited to regulated activity
with vulnerable groups, then barring would not be an issue.
Robert Lightfoot, former head of NASA, said it succinctly in his parting speech in April 2018: Protecting against risk and being safe are not the same thing ... [W]e must move from risk management to risk leadership. From a risk management perspective, the safest place to be is on the ground. From a risk leadership perspective, I believe thats the worst place [we] can be.
