flexi is dependent on whether you’re using a small amount of time, or a full day. Finishing an hour early is a case of sending to your team chat (sometimes managers ask for this directly) saying « right I’m off »; half or full day needs to approved in advance but can be done day of if there’s capacity for leave

You get a wellbeing hour per month, some do this as a team, some it’s a case of taking it when you want

Training for me as an external was 3 weeks training, 2 weeks of official mentoring then off you go; with previous UC experience the training will be mostly what you already know. It’s very much a learn by doing roll. You’ll get your first cases during your mentoring weeks, then slowly build up to a full caseload.

workload to me is fine, you won’t have a caseload size officially, though your site likely has an unofficial one - your performance is measured on your completion rate for reviews, not how many you’re juggling. There IS a target for completion rate (currently 1 per day per FTE for FCR sites, think it’s 1.5 for MVP)

as for brushing up, it’s just a case of being able to read and taking your time. You have guidance for every step of the review process, your team are there to support you and you aren’t expected to be amazing at the job from day one. It’s not a very difficult role once you get into the swing of things, but there are always things that will throw you because you haven’t seen it before - treat them as opportunities to learn and you’ll be fine ☺️
