In Finland the employers allowed to monitor the correspondence staff.

President Tarja Halonen of Finland on 13 March signed a law allowing employers to monitor employees in the case of correspondence, if the latter are suspected of misconduct or violations, transmits AFP.
Parliament approved a law known as Lex Nokia ( "The Act Nokia"), last week by 96 votes in favor with 56 against. Law received its name because of a rumor that Nokia threatened to leave the country if he will not be accepted. Nokia itself denies this rumor.
The law applies not only to companies. It allows schools, libraries and operators to monitor users. They will not be able to directly read the mail, but, for example, can check the size of the annex to the letter or the recipient to know whether the letter is not sent to competitors.
Lex Nokia aims to prevent industrial espionage, illegal transfer of intellectual property and distribution of malicious software on corporate networks. It gave rise to serious criticism of human rights defenders. In their view, the law gives companies more rights than the police.
