How did you negotiate an exit settlement? Things have got nasty…

[Ta1001]

New manager, not coped well with them, very critical. I’ve had enough and want out. Any scope for this? I think they want me gone too

Unless you’re very senior or have some kind of pending legal case, I’d be surprised if you could get a payout.

You might be able to negotiate leaving with a shorter notice period, and you should be paid out for your accrued vacation.

You will need to consider that they have all the power in this one. Unless there is caste-iron corroborated evidence of discrimination (your description doesn't appear to be anything related to discrimination under the Equality Act (2010), rather it's a personality clash), you won't get any payout on the strength of not getting on with your manager.

if it's unbearable, the most expeditious and healthy approach is to find a post elsewhere and make sure you get a clean reference from them, rather than embarking on a claim that doesn't hold water.

if you aren't yet really ready to leave, just feeling really demotivated, you could try lodging a grievance to see if it brings into the open what issues your new manager has against you.

@daisychain01 thanks, how would lodging a grievance help?

Call ACAS and get advice, it's free.
If you're in a union, contact them.
If you're not in a union, consider checking what the minimum time is to be a member before you can full support from them (mine is 3 months).
Then spend the next 3 months gathering evidence while also job hunting.
That is if you think you're being bullied or have another good reason to raise a grievance (look at your employers grievance policy).
But basically, call ACAS and talk to them.

Based on the very limited information you've posted (appreciate that you may not want to post more), you have a new manager who is already very critical and causing you to want to leave. They must be very unpleasant to make you feel that way. It is a very common occurrence for someone new coming in to want to force out legacy staff to bring in their crew.

if you are a long standing employee, lodging a grievance can be a powerful way to highlight someone's poor behaviour, and you may not feel at liberty to confront the manager directly. Your employer will normally investigate your situation to find out the truth behind it and decide if they need to address the problem.

a grievance also serves to formalise concerns and is the precursor to Tribunal. Although you don't have grounds for a claim, it still gets them to sit up and take notice. And what does it cost you to submit it, nothing, so it's cathartic and helps you to move forward if nothing else.
