What does "Redundancy" mean?

Thank you for looking out for me cuz. I really appreciate it. Don't know if mom said but I've got another job now still retail but it's going well. xxxx

It’s good for employment protection.. Boss can’t just fire you for no work. And hire his relative the next day..
if they use redundancy as an excuse they can’t refill the position

the state of being no longer in employment because there is no more work available.
plural noun: redundancies
"the factory's workers face redundancy"

Dunno usually in the uk redundancy is better then been straight fired as you usually get a redundancy package..like a month or two wages or whatever. Often companies when making cuts offer volentry redundancy packs before aswel to give a chance to those that may want to leave before forcing it

Basically it's been fired but with a bit of cash (and not because your inept at your job). There are exceptions though like if a company goes under you'd be made redundant without a package ect That's uk anyway so I assume it's the same elsewhere

What part don’t you understand? Why it happened or what it means?

No longer required

Redundant means their position/function is no longer required/exists.

Essentially, no more work available.

Redundant means fired

redundancy = stress and worry ,,you dont have to worry just yet plenty of years of work after you finish your education xx

Likely they were laid off because the company is downsizing. This could be due to covid-19 where a lot of companies had to close offices because of loss of profits. It sucks, but sadly, that's capitalism for you. I'm sure they could still afford to pay him if the shareholders and CEOs didn't get a big fat paycheck.
