I an a non EU national and am employed in the Netherlands and have a Netherlands work permit.
My Dutch Employer has obtained a project in the Czech republic and wants to send me there to work at a local Bank (I would be still employed by the Dutch Employer).

Do I need to have a work permit for Czech republic? Will the Netherlands work permit hold good given that both are Schengen states? My Dutch employer would be billing me to the Czech company for the work done by me.

Does having a NL work permit mean that I can work in any Schengen country for that employer?

Thanks in advance
