I took a habit of working for few minutes and taking a small rest after(of course the time tracker will be off) but this resulted in a low activity segments, so for exemple I work 3 or 4 minutes in an interval of 10 minutes (let's say 13h00 to 13h10 worked 3 minutes and got billed for 10 minutes), this result in an activity level 3 or 4, then I stop working (closing the time tracker off again)
This doesn't seem to bother my client since I always get the work done with an execellent quality but now I'm not sure if it's really a good way of doing it even if I checked the oDesk TOS and there was nothing forbidding it.
Then I somehow think of people working in an office even if they are paid for 8 hours of work they always work less than that since they take coffee rest, go eat, talk to each other etc..
Question is, is it somehow fine or legal to maintain this working habbit ?
The bottom line is it's up to your client - and the one way to be sure it's OK is to communicate with them. Explain that's the way you work and ask them if they're happy with that. It also depends on your hourly rate - if you work 5 minutes out of 10 but charge half as much as you should per hour, then that's fine.If not, please don't assume that all other workers work like you do
So what you're saying is that for every hour you actually work, you charge two and a half hours.
People in an office may work less than a full eight hours but I don't think they only work three hours.
I guess if your client doesn't complain, you can continue to get away with it but it doesn't really strike me as the ethical thing to do.
