Sorry that my English is bad.

But what does employment rate down and Unemployment rate improve means?

Assume that you have initially 100 people employed and then you retrenched 20. So the total employment is down, right? The unemployment rate is now 20/100 = 0.2.  

Then in the next quarter, another 10 got retrenched. So the total employment is again down. But now the unemployment rate is 10/80=0.125, so it is down.

They're talking about rate and not total unemployment. If it is total unemployment then it'll actually be (20+10) out of 100, which is up.

Of course, this is simplified because it doesn't take into account that the original 20 who is retrenched may have found jobs but this is just for illustration.
