Vantaggi
Some managers are awesome and will do their best for their employees but they are few and far between. Opportunity for employment across the UK and globally. Plenty of development opportunities - if you're able to get the time out of the office to go on the course.
Svantaggi
Some managers force out employees they don't personally like (5 since January where I am now) Communication is awful Compensation is probably the worst of any high street bank. They allegedly base it on the average across the high street. Individual teams are so worried about their own little fiefdom and "beating" other teams that they might as well have stuck with incentivised selling. Good employees lose out to employees who interview well but don't have the skills to back up the interview. No promotion based on merit either - which means no promotion essentially unless you don't realise that a branch/department is bad and apply there and no-one else has. Manager will rate you badly because they have lost your employee file. (Seriously. I thought the manager at a previous employer who was trying to get me to help him commit industrial espionage was bad but then I moved branches with you guys and my current manager is worse. At least the other guy could communicate openly and accurately, even if it wasn't always above board.)
