Honestly, I think it's mostly to assert their power over workers. It's natural for people to do this if they can: it feels good and makes them feel in control, even if it's not very effective or is downright detrimental to the bottom line. It's also natural to search for plausible excuses for such behavior - nobody wants to admit that they just get a boner (metaphorically) from bossing others around. Just my general opinion, I have too little information to say if the tracking, in this case, is actually a rational and net-positive policy and not someone's power trip.
