How to set up a process with remote employees?

Question

Work organization

There are various tasks for the project, complex, easy ...
Everything is divided into tasks, in fact, we need a person on a permanent basis who would deal with these tasks. Due to the circumstances, it is not possible to imprison a person for a salary ... Only a remote location is needed.
Here's how to take into account the work performed and pay for it in this case?
It only comes to mind to take a specific task, to find out the time X the cost of an hour, and so iteratively throughout. But one minus needs to be constantly monitored so that the estimation is adequate.

Answer 1

You can use special services, such as a crm system. Where the employee can put the importance of the task, the start time (when the task was taken into development) and the end time (when the task was completed). You will really see which tasks were important, which were not so much and how much time was spent on work.

Answer 2

Prioritizing importance by an employee is somehow not right if there is a clear plan of tasks that just need to be done first, and the rest can be done later ...
Yes, but it turns out, for example, the task was taken at 10 am and closed after 2 days at 12 am. Real work can be about 6 hours. The rest of the time I could go anywhere for everyday problems, not wanting to do it faster, etc. And then how to determine how much to pay for this work?
