I worked with and without a tracker. I wanted to work without a tracker, you understand that people trust you, but as soon as tracking was introduced, interest in the work began to decline.
I also work where there are trackers, but there is a but: as explained, the tracker is for adjusting work: if you take more time on a particular task, then we will take this into account in the deadlines. This position is nice, because not all tasks can be closed in the same time. And it is nice when they pay extra for overtime, because sometimes you have to work more. So you need to take these points into account.
In principle, when it comes to deadlines, I’m not against trackers. When it comes to tracking what I’m doing on the PC, the work doesn’t stick. After all, sometimes to do something you have to go to sites where you have saved refs.
