Sacked today!

[cntxy81]

I need your advice.

Today I have been called to a meeting and out of the blue I have been told that they want to sack me.
I believe they have no right on claiming under-performance as I am being measured against a made up sales target that I have disputed multiple times.
In the meeting, I was given the option of voluntary redundancy. I didn’t agree nor disagree, I told them I wanted to review my options.
My notice period as per my contract is 3 months and I had been with my company for 2.5 years.
As soon as I arrived home (my emails have been blocked and my colleagues made aware that I had already left the company) I received an email to my personal address telling me something like “As per your redundancy request 3 months ago today is your last day, we will pay you a sum of XXX (equating to 3 months salary).
I know the XXX money is tax free, which benefits me. However, I find this very unfair and I am considering sending them an email saying something like “I accept to give my redundancy notice today as long as I can keep the XXX lamp sum”
Please give me some advice.

I am a little confused as to how your company can say they want to sack you but also give you the option of voluntary redundancy. There is either an issue with your performance for which they need to go down a disciplinary route or if there is a need to make redundancies in accordance with criteria that create a redundancy situation then they need to go through a redundancy consultation.

If there is a redundancy situation then what you have detailed from the email you received is an incorrect calculation. You should receive at the minimum a redundancy payment based on length of service and age which is not liable to tax and national insurance deduction, then if you are not expected to work your notice then this should be paid in lieu which will be subject to tax and national insurance deductions plus pay for any accrued but untaken holiday.
