It didn't suggest any such thing though. It said joke and laugh less. It didn't forbid them.

Humor that doesn't offend can be hard to pull off. If you crack jokes regularly, odds are high some of them will be offensive.

Most people are quick to assume you are laughing at them, not with them. So if you are laughing a lot at work, odds are good someone will take that as mocking, as disrespect, as you not being adequately serious about the job.

If you are careful with humor, you can do good things with it. People who joke habitually are probably not being careful with it.

Sounds like maybe you need some new coworkers because where I work we laugh and joke around all the time and nobody ever gets offended (or offers offense).
