Not quite. There is a larger amount of H (often with random mobs) than is normal for a straight-out romance game, but the actual heroine stories are solid. I'm pretty sure the people who labeled them nukige only played the prologue and/or common path.
Edit: The only real downside is that the protagonists are kind of man-whores at times (the first game in particular has this). However, there is at least one workplace romance in each of the Hataraku Otona games, with Hataraku Otaku tending to focus on the bar.
