Your job or girlfriend?

You want this job. And she, too. Let's try to speculate on what to do in order to remain friends in this delicate situation at any outcome of the matter.

To speak or not?

The boss hinted at you about a possible increase. And then suddenly it turns out that in this way he also encouraged your closest friend.
What to do? Try not to start from the very beginning that you have a choice - a friend or a job. One does not contradict the other at all. However, if day and night to reflect on this topic, very soon it will start to seem that your girlfriend deliberately sat down, and this is not true. Also, there is no reason for oppressive feelings of guilt in front of her. To exclude all the misunderstandings, invite her to a cup of coffee and, as if in passing, say: "By the way, our-something called me to myself and ..." Bring the news about your anticipated increase as unconcerned as possible. Your friend is clever: she will understand everything perfectly, and you will laugh at the "trick" of the boss together.

Interview: how to behave?

Your main goal at this stage is to submit your own professional qualities in the best possible light. The same is required from a friend. Not more, but no less.
What to do? The only thing that you can help her, is to assure in all ways that, in any event, your relationship will not change. And, of course, it's up to you if you improve it, to fulfill your promise exactly.

You got a promotion

Congratulations! That's just now say the best friend? Be as correct as possible. Put yourself in her place and tell the news the way you would prefer to hear it yourself. That is, no one should even have a shadow of doubt in your sincerity. Stick to this line of behavior - and a friend will surely rejoice for you.
What to do? Now the girlfriend is your direct subordinate. Nevertheless, she is still a close person to you. Be sure to listen to her suggestions for work, go back to the ideas she told the previous boss, even if you heard about them more than any of your colleagues. As often as possible, emphasize that you value her with help and advice now, in such a difficult period for you.

She was promoted

Today she is on horseback, so just congratulate her and have fun at a party in honor of the new appointment. A few days later, "take a break" to assess how well you prepared for a responsible interview. Analyze what mistakes you made when you were trying to improve.
What to do? Ask for a friend's resume and see how it is composed, ask what tactics she followed during a meeting with the leadership that she said and so on. All this is sure to come in handy in the future, wherever you work. And, of course, do not even think about getting upset.

If you both flew

You have a wonderful chance to cement the bonds of friendship, crying to each other in the vest. Then go to a bar or club, preferably with those who are able to comfort you. Now, replenishing the life baggage with new experience, you can without fear set off on a quest for a new employer, since the current, reptile and scoundrel, did not appreciate such fine professionals.
