the germans use a system with their guys where the prices are worked out by the time it takes to do the tiling job and you are paid accordingly these rates are agreed by the employers and the unions just wondering if you have the same system in sweden
Well, most employees get either a fixed per hour wage plus extra pay for overtime etc, or a performance based salary. Performance based salary tends to work roughly like this:
You get a basic salary, which is kind of low, but you can survive on it. When you're working, you get a certain number of objects to complete within a certain timeframe. Say, for example, that you get one month to complete x number of bathrooms. If you finish exactly on time, you get a predetermined bonus. For every day you finish early, your bonus increases in size with predetermined percentage, up to a point. Vice versa, for every day you finish late, the bonus shrinks, and after a predetermined number of days, the bonus part of the salary disapears entirely, or almost entirely, depending on circumstances.
That's simplified, but roughly how it works for many construction workers in Sweden. Mainly used on commercial jobs.
So, the short of it: Normally, wages are either fixed per hour, or determined by how fast you can complete a given job, rather than how long a job should take. The target dates are normally calculated and agreed upon by both the employers and the unions, so that they're resonable, and there are quite strict guidelines on how to do that.
Small subcontractors normally work on either per hour or per sqm, while larger subcontractors commonly take out a per sqm price, while paying their employees performance based salaries.
