. @Jiimmii There's an updated version of the document @grumpydogwoman linked here. You should read it, although I'm afraid it will not make happy reading for you. The gist of it is that accepting a caution for possession of a Class A drug is likely to result in a prohibition order being issued. 'Likely to' but not necessarily, the discipline panel will take into account "the nature and gravity of the offence, its circumstances and any mitigating circumstances...". Your union needs to give you proper legal advice on this. Some of things the union rep has told you seem surprising to me. Not telling your employer? Really, when discovered that simply makes your position more worse. Honesty and transparency will be mitigating factors both in the school's decision and, should it come to it, a formal panel considering prohibition. Does the union rep have any reason to believe that if you accepted a Settlement Agreement from the school ("taking 3 months wages and resigning right now to make the whole investigation go away, to get out of my school's hair") they wouldn't refer you to the teacher discipline panel? Heads have statutory duties to make referrals. In my school I can't imagine we would consider for one minute paying 3 months salary to a teacher cautioned for possession of a Class A drug. . .
