Sock knitting again!

I am still working on that same sock and am still having problems!! What does it mean when you are turning the heel and it says to WORK the last 2 stitches??Not knit or purl but WORK?

Usually “work” means to do them in whatever you’ve been doing them in. So if the purl side is facing you, you purl them. If the knit side is facing, knit them.
