If you track the time of your remote workers, then it means they are full time employee.
If they are full time employee, then they should be paid the proper hourly rate of WHERE your business is located at. [Are you paying them the same rate your state mandates you to?]
I see a lot of employers right now have mixed up with this idea... they say they're full time employee, but they are not paid as much as what the employer's state mandated.
And when someone makes a fuss, they will avert the status to "contractor", which falls into different category. [As such, contractors are not paid on the clock, but only responsible of the output/deliverables, no matter if it takes them 10 mins to do the entire job or takes them 12 hrs, thus time tracking should not be implemented.]
Look it all up, even ask a labor/employment lawyers, just in case you think I am making this up.
As to my previous arguments, you cannot track productivity and creativity. So many times, when employer starts tracking their time, their quality of work fades. You think you prove your guts right, when u have hunch of them slacking hours, but it's not really the case; they slack because amidst all the quality works they have done to finish the task properly AND early so they can reward themselves some free time, now you're taking that away from them.
I am saying that based on the interview I personally conducted with remote workers from your favorite outsourcing country. A few of them literally drops the job when they their employer starts tracking them.
And here I see some employers are asking why they just disappear without a reason. LMAO!
