I don't pay any attention to the opinions of Trek review sites. Some of them think it's cool to completely trash an episode, especially if they don't like the series overall.
Like many Trek episodes, Workforce
presents some interesting ideas, some nice visuals, and is generally entertaining. Some of it works, some of it doesn't.Though I probably would have liked it a little more if it hadn't been a two-parter, it feels like there's some padding to me.
But Ralph Malph as a bad guy is worth something.
