Immigration law refers to national government policies which control the phenomenon of immigration to their country.
Labour law (also labor law or employment law) mediates the relationship between workers (employees), employers, trade unions and the government. Collective labour law relates to the tripartite relationship between employee, employer and union. Second, individual labour law concerns employees' rights at work and through the contract for work. The labour movement has been instrumental in the enacting of laws protecting labour rights in the 19th and 20th centuries. Labour rights have been integral to the social and economic development since the Industrial Revolution. Employment standards are social norms (in some cases also technical standards) for the minimum socially acceptable conditions under which employees or contractors will work. Government agencies (such as the former U.S. Employment Standards Administration) enforce employment standards codified by labour law (legislative, regulatory, or judicial).
Work permit is a generic term for a legal authorization which allows a person to take employment. It is most often used in reference to instances where a person is given permission to work in a country where one does not hold citizenship, but is also used in reference to minors, who in some jurisdictions require a permit in order to legally work due to Child Labor laws. Within an industry, a work permit may be required to execute certain functions within a factory outside of normal operational tasks (such as maintenance tasks) - in some places they might be called Permit to Work (PTW).
Currently, every EU country has a different process for granting work permits to nationals of non-EU countries. To address this issue, the European Commission began work in 1999 on developing an EU-wide process for the entry of non-EU nationals into the work force. In October 2007, they adopted a proposal to introduce a work permit similar to the United States' "Green Card" program, called the "Blue Card". It is similar to the UK's Highly Skilled Migrant Programme, with the exception that it will require an employment contract in place prior to migration. After two years in the first country, the migrant will be allowed to move and work in another EU country, and can sum the number of years spent in the EU for purposes of residency. This new card will abolish work permits across the EU and centralize the issuing from Brussels.
The National Football League (NFL) is a professional American football league composed of 32 teams divided equally between the National Football Conference (NFC) and the American Football Conference (AFC). The highest level of professional football in the world, the NFL runs a 17-week regular season from the week after Labor Day to the week after Christmas, with each team playing sixteen games and having one bye week. Out of the league's 32 teams, six (four division winners and two wild-card teams) from each conference compete in the NFL playoffs, a single-elimination tournament culminating in the Super Bowl, played between the champions of the NFC and AFC. The champions of the Super Bowl are awarded the Vince Lombardi Trophy; various other awards exist to recognize individual players and coaches. Most games are played on Sunday afternoons; some games are also played on Mondays and Thursdays during the regular season. There are games on Saturdays during the last few weeks of the regular season and the first two playoff weekends.
The NFL was formed on August 20, 1920, as the American Professional Football Conference; the league changed its name to the American Professional Football Association (APFA) on September 17, 1920, and changed its name to the National Football League on June 24, 1922, after spending the 1920 and 1921 seasons as the APFA. In 1966, the NFL agreed to merge with the rival American Football League (AFL), effective 1970; the first Super Bowl was held at the end of that same season in January 1967. Today, the NFL has the highest average attendance (67,591) of any professional sports league in the world and is the most popular sports league in the United States. The Super Bowl is among the biggest club sporting events in the world and individual Super Bowl games account for many of the most-watched programs in American history. At the corporate level, the NFL is an nonprofit 501(c)(6) association. The NFL's executive officer is the commissioner, who has broad authority in governing the league.
