Pretty much everyone technically dislikes their job. If it were fun, you wouldn’t get paid for it.
When people say they “love” their job, they mean relative to other jobs. It doesn’t mean they’d rather be at work than at an amusement park or on vacation.
I’m sure there are a few freaks out there that are an exception to the rule. Older generations seem to consider it distasteful to admit to hating working, so you have to take what they say with a grain of salt.
