Labour mobility is not the same as worker mobility and a posted worker is rarely in a posting. Whenever an employee or contractor crosses an internal EU border for work purposes, it is necessary to resolve conflicts between the different legal systems. Under which rules do we calculate his or her working time, and especially overtime, when the weekly norm is 40 hours in one Member State, 35 hours in another, and 48 hours in yet another? Where do we pay social security contributions and at what rate and on what basis? Whether and where to make advance payments of income tax? How to determine the components and the amount of remuneration?

Light form, lots of examples, Q&A.
