The talks between the NHL and NHLPA are at a standstill, but there is news regarding at least one item that the NHL wants. The New York Post has learned that in the NHL's proposal it includes something called "management rights:"
... the NHL proposals feature a "management rights" clause under which the league would assume unilateral power over issues including realignment, scheduling and playoff format.
The union refused to give its assent last year to the league's proposed realignment plan for 2012-13 that would have created a four-conference (division) format, with attendant changes in scheduling and playoff structure.
Realignment was an issue last year since the Atlanta Thrashers moved to become the Winnipeg Jets, and the league was forced to rearrange the divisions for the 2012-13 season.
This "management rights" item would give the NHL a lot of power in how the league is set up, and if a team relocates then the NHL would be able to decide by themselves where that new team would be placed. Also, this move would allow the NHL to create new criteria as for who makes the playoffs with four divisions, and not have to consult with the NHLPA.
