Exactly! That's inconvenient especially when you're doing home based job. Our friend was inclined to buy their own power generators so as not to hamper her online classes. I've experienced the same when I needed to pass 15 articles/ day when we had 3 days power black out due to low pressure. The result, I got a penalty from our company. That's the sad part when there's power interruption and they won't accept reasons. I decided to quit and do blogging instead where I can work in my own pace and less worries.
