Use Of Your Own Accounts While Working On Your Boss's Time...
It doesn't take a genius to work out that if you are doing your own socializing on your work time, you are simply stealing time from your boss.
Some people believe they have a right to socialize in work's time, in fact, I once believed that myself in my early working days. But most people quickly realize you don't bite the hand that feeds you.
The thing about Facebook, Twitter and all the other social networks is that you publicly display to the world the exact time at which you
wrote published your comments. It's not going to take much to work out that you should have been working at this time!
There are some modern companies who understand that some flexibility here is important as part of the employee's welfare, in the same way that if you make one or two quick personal calls per day, no-one is going to say much. But you have to really police this yourself - make sure that you spend only a few minutes doing this at a time, and make it part of a natural break in your work. Once or twice a day is plenty - there is no-one in your life who needs you that badly who wouldn't phone you or get someone to call you in a genuine emergency!
Plus, if you make a point of tweeting or posting something positive about your company or your work in that time, you're going to have a way out if your boss decides to pick on you that day.
It all boils down to respect. Sadly some employees wait to feel respected instead of earning respect... it never comes and then it's easy to justify 2 or 3 hours or more of faffing about on the net doing your social networking... once you lose your job over it, you still maintain you haven't done anything wrong!
TIP: Make sure you earn respect - you do this by doing things that are respectable! Then you can maintain your social life through work time, discretely and without interfering with your output.
