Its a very common thing in US companies and the big 4 in the UK even for normal non redundancy leavers - does seem odd almost like the Company is admitting guilt.
In a redundancy case I might say well then provide me will all the paperwork you have on file I will get my lawyer fried to check this over or we can sign the compromise agreement now for lets say 4 months salary.
And also the comment right about the "unnerving culture" is a bit of a red flag.
Not sure about the UK, but in the US consulting has a lifecycle. Very few hires stick it out for more than a few years. But that’s a feature not a bug. It’s not unusual for the Big 3 to help find you a job at a client. And why not? Now they have a lead for new work at the client. And the anti-disparagement makes sure when you’re talking to coworkers at your new job you talk about how great your time was and pass any interested candidates back to your old firm as new hires. Again, now the consulting firm has another contact at the client to help drum up business.
