Is it ok to correct a co-workers grammar when they are speaking to an applicant?

No, it's not okay. Even though the co-worker should be using correct grammar, to point this out with other people around is humiliating. The proper way to handle this situation would be to allow the co-worker to finish what he/she is doing and then, when no one else is around, gently mention it.

No. You both should provide a united front to a prospective employee.

However, if someone corrected your grammar, you should let it slide and not make a big deal about it. Even if they were wrong, even if it was rude for your co-worker to correct you, it is worse for you to get upset about something so trivial. Especially if you did this in front of the applicant!

Instead, make sure your grammar is correct. Read through the first few pages of a Webster's Dictionary and take the time to better your command of the English language.

If you don't present your co-worker with such an opportunity again, you won't be embarassed.

Better shape up your own first. Correct grammar would be "Is it ok to correct a co-worker's grammar when HE OR SHE is speaking to an applicant?"

It is never OK to correct someone else's grammar - especially when in front of another person! The only way you should be correcting people's grammatical errors is if you are an English teacher!

You should have written "Is it okay to correct a co-worker's grammar when he or she is speaking to an applicant?"

Perhaps you are not the expert in language which you believe yourself to be.

No you shouldnt do it in front of the applicant. It actually undermines that person in a professional manner and gives the applicant the wrong/bad impression of the person interviewing them. But for sure you should definitely correct the gammar in private because it is a bad representation of them and the company overall. Its just so they know for the next time. Hope I helped.

Absolutely not. You would be shaming your co-worker and also giving the applicant a poor impression of relations between workers

No i think its rude to correct a co-worker. I'm sure you would be embarrassed if you had to be correct by one of your co-workers or someone of your level.

First make sure the applicant is gone. It may also help if you're aware of your classmate's openness to be corrected. Some folks use to take offense to it.

I would be inclined to wait until the applicant has left, and then suggest a correction.
