Common courtesy (Professional behavior)

So, how many of you- employees, receive a call back from an employer after you have applied for a position? The answer will surprise you.
From my personal experience and that of my close friends, I received a disturbing statistic: Employers rarely give them a call back, whether its great news- you are hired or bad news-“you are not the person we are looking for”. Some employers call 3 weeks after an interview with the news of “you are not what we are looking for”. Other employers just don’t call at all.
Now, why do you ask, it is important for employers to give call backs? The answer is pretty simple, so that the employee will not feel like in limbo and can move on to the next employment opportunity. From the employer side: showing a common courtesy and being professional- to at least inform the employee of the interview outcome: good or bad, gives some kind of positive image, even if the person interviewed did not attain the employment with the particular employer.
Some of my friends,like my best friend decided to take a more proactive approach: she would call the employer a week after interview or 3 days after. On the other hand my other friends were just disappointed by the fact that the employers were not professional and decided never to deal with those employers ever again and never refer anyone for a job interview for that employer.
So, what is your opinion on this matter? Do you use proactive approach or just move on to another employment opportunity? Please feel free to share your experience! 😁
