How important it is to be accepted at your work place?

Greetings,Please allow me to answer your question in my own point of view.To me being accepted in a workplace is like having a haven.It can also boast your self confidence,it allows you to fully develop your potentials,with cooperation from everyone you can perform your job well, and you are assured that their will be no hindrance when it comes to communication.

it is very important because you will have an excellent communication with your colleagues if you acceptable

That really depends. Firstly on how important it is to you personally to be accepted and what being accepted means to YOU. Is accepted "feeling good in the team" or "taking joint vacations and barbecues with co-workers' families"? Secondly it depends on how crucial being accepted is to your work, your results and group work / results. So, everyone has to give it a thought and give him/herself an answer for there is no universal answer / solution to your question ;)
