Re: Internet at work ..
Also private schools. 
It’s called multi-tasking. 
Our Urdu teacher used to write a line on the blackboard and our task was to write it neatly in our notebooks (copies) over and over until the period was over. It was called ‘likhaai’. Meanwhile she was busy knitting.
I am so thankful to her. Unn ki vajah se hamain khoosh-khati aa gaee. 
And on the original topic.
This question has always intrigued me.
Most people on this forum are constantly connected at work.
I don’t know how they keep their focus on work.
It is so tempting to keep checking back on updates and responses every 2 minutes.
And no, multi-tasking does not work and has been discredited as counter-productive.
BTW, this is not unique to Pakistan.
Visit any online forum and the same theme repeats.
The cost of lost productivity because of personal internet usage at work must be in the billions of dollars.
