Tl;dr: no, you're reading this, because there's nothing funny about hitting an animal with a shovel and I can't believe I have to say that.
The snouts of crocodilians are some of the most innervated tissues in the entire animal kingdom. They are more sensitive than human fingertips. They can detect the tiniest pressure changes in the water; an alligator in the pitch-black dark can sense the ripples from a single drop of water in an aquarium, even when their hearing and sense of smell are blocked. Their faces are covered with tiny sensory organs. The epidermis is 40% thinner immediately above these tiny sensory organs, while the keratin layer is 60% thinner and more compact. Here's a map of that nerve tissue:
And this guy knows that because when he hits them with the shovel, the moment of impact is on the side of the face. He is making the decision to hurt these animals.
In the stills, you can see that he's going in from the side and the front of the mouth. He's not smacking them on the tail or flank, he's hitting them in the face. These animals are afraid of him, because this man is coming in with a shovel and hurting them, on purpose. Why is the one in that second still opening its mouth and charging? Because it is afraid of the man with the shovel, who has come here to hit it.
Seriously, this is toddler stuff. Did you not learn in preschool that it hurts when you hit things? Did your parents never say "no, we don't hit the doggy, he doesn't like that?" The crocodilians don't like it either! You see how many of them fled or took defensive positions immediately? That's not a good thing in captive animal management! You want them to NOT be terrified of you because a terrified animal lashes out.
Think for a moment about your fingertips. You need those for typing, for scrolling, for touching, for finding out about the world. Now imagine me smacking the hell out of them with a shovel because I wanted you to move. Not fun, right? You'd call me abusive for doing that right? Perhaps I could have found a less-aversive way to get you to move rather than beating you with a shovel. Perhaps I should have learned your body language better, or asked you to move with auditory cues, targeting, anything else other than beating such a sensitive body part with a shovel. Crocodilians are quite trainable and easy to move in zoological settings. Here's a video from Reid Park Zoo showing exactly how their alligator targets and follows a pole:
And because crocodilians are so intelligent and have such strong sensory input, you can move them without having to be in the same room. When I was job shadowing at a zoo many years back, I moved a fully grown male Cuban crocodile away from the nest he was guarding with nothing more than some splashes in the off-exhibit water. I was fourteen and had never worked with a croc of any kind before, and I was able to do it because the zoo had trained their animals to shift. That's basic predator safety. (I mean it's basic animal safety, but I don't want to get into that. I'm talking about how bad of a zookeeper you have to be to think that the only way to shift crocodilians is to hit them.)
Even baby alligators can learn how to follow a target.
Here's a video of Zoo Australia moving the largest species crocodilian, a huge male saltwater croc. This is a far more dangerous procedure, and surprisingly, it can be done without hitting them! You'll notice they do use physical cues here, like the top jaw rope, which is aversive- but also notice where it sits. Compare it to the nerve map above, and the locations where the animals are being hit.
So yeah, this is abusive, and if you think it's not, go smack your hands with a shovel and see how you feel after. You won't like it! Also, maybe we don't hit things, because we are grown ups and have different tools in our skillset. If my one-year-old niece can gently pet a lizard, this grown-ass zookeeper can learn some basic animal handling skills.
