But I know many workers who are using their work time for trading if they are trader if they work on the office that have internet connection theh do that.
All in all, it still a bad idea to trade at work because you can't focus on two things at a workplace and also you can't excel on multi-tasking, one should be prioritized and monitored. So use only free time to trade. If you badly needed it then make a free time for yourself while making your day still productive.
