Have you ever opened your mouth, in all innocence, said something to your boss or senior and regreted the same every single day it flashes through your mind? Well, sometimes you might get away with some things if it is family or friends or even business partners you are talking . It never is the same with your boss.

Your boss at all times expects results, period! Rarely would the boss want to know how hard or how easy something could be done or achieved. So for guarantee of your security, there are some things you should learn not not say. In fact, if you could avoid frequent communication with the boss, sometime, the better. But if you must talk, then here are a few No-No phrases you should never line your discussion with.

1. "I need a raise."
Never enter salary negotiations talking about what you need -- because of rising costs or a new expense, for instance. Your employer doesn't care about your financial problems. A raise request should always be supported by evidence of what you've achieved for the company -- along with information about what people with your responsibilities typically earn. The boss would want to reward excellence, wouldn't he?

2. “That just isn’t possible.”
Always speak to your boss in terms of what can be done. For instance, rather than saying “We can’t get this done by Friday,” say “We could definitely get this done by Monday. When you talk to your boss, think in terms of solving problems, not in terms of putting problems on them.

3. “I can’t stand working with ____.”

Complaining about a coworker's personality usually reflects more poorly on you than on the coworker. Don’t make these kinds of conflicts your boss’s problem. Of course, management is interested in problems that jeopardize the company's ability to function. If you have to speak to HR about a problem such as a colleague's threatening, illegal or unethical behavior, keep your tone professional and the focus on work -- not personal issues.

4. “I partied too hard last night -- I'm so hung over!”

Never share the sordid details of your night about town with your boss. Even if you have a friendly relationship, he’s just as likely to react with (unspoken) disdain as sympathy. Drink some coffee, pretend you are fine, cover it all up. Maintaining a solid veneer of professionalism will pay off when it's time to discuss promotions.

5. “It’s not my fault.”
Are you a whiny 8-year-old or a take-charge professional? Assume responsibility and take steps to fix a problem that you did, in fact, create. And if you are being wrongly blamed for a problem, saying “Let’s get to the bottom of this” or “What can we do to make it right?” is much more effective than saying “It’s not my fault.”

6. "I don't know.”
If your boss asks you a question you can’t answer, the correct response is not "I don't know." It's "I'll find out right away." If you don't know, he could easily find someone who 'knows'.

7. “But we've always done it this way."
You may find yourself with a new boss who wants to try new things -- and the best way to present yourself on the spot, utter the "we do it this way because this is the way we do it". When a brainstorming session takes place, be part of it and stay open to new ideas. If you have concerns about a new idea's feasibility, say "I think for this to work, we will have to…" Don't kill new ideas with negativity.

8 “I saw your status update last night..”
It is said your boss is not your friend. In modern workplaces, hierarchical structures are often less rigid, and bosses will often end up in semisocial situations with their direct reports. Smart workers will draw the line at "oversharing" -- definitely something to keep in mind if you're connecting to your company's managers on social networks like Facebook.

So like the wise men said, think before you speak.
