Whether you work at a firm that employs hundreds of workers or just a handful, it is important to be mindful of your fellow employee. Everyone has the right to expect respectful treatment on the job, no matter what it is that they do. Here are some things you should never say to one of your co-workers:

“You really should exercise more”

It is very bad form to discuss a person’s weight, even if you are sincerely worried about their health. People with a few extra pounds are not always the stereotypical lazy slob who eats poorly; there are several medical conditions that can cause a person to gain weight and there is little that can be done about it. Try to put yourself in their shoes. Chances are, you wouldn’t want people to say something like that to you.

“You’re not religious, are you?”

Whether a person practices a certain religion, or none at all, is their own choice. Religion can be a touchy subject that causes people to argue. This is not the sort of thing you want to possibly sour the relationship you have with your co-workers, so leave religion out of your water-cooler conversation.

“You’re not a Trump supporter, are you?”

Politics is an area that can even cause old friends to quarrel, let alone people who simply work together. With the considerable political divide in the country these days, this is another subject best left outside of the office.

“Don’t get mad! It was just a joke!”

We all have different senses of humor. Some of us like a nice, harmless joke, while others are amused by some of the raunchiest, filthiest material imaginable. At the office, you should take a neutral stance. There is nothing wrong with an occasional joke, but be mindful of saying something that someone could take the wrong way. No joke is worth lingering hurt feelings and the effect they can have on your ability to work together.
