Good news! Just got a phone call from work, the client found the missing $$$ (and from the sound of it it was $$$) so that's a relief to say the least. Change in the attitude of the carer lead was... a thing. But a cordial conversation was had and she's taken me off that client, so all well there.
I'd put in an application to join a union this morning and I'll keep on with it, as knowing aged care odds are that Something Will Happen.
But now I can do dinner tonight and really enjoy it, not just try and use it as a distraction!
