NHL Players Union Threatens Lockout as Labor Negotiations Stall In a move that could potentially disrupt the upcoming hockey season, the National Hockey League Players' Association (NHLPA) has issued a warning that it may call a lockout if labor negotiations with the NHL owners fail to yield a new collective bargaining agreement. The current CBA is set to expire in September, and with no signs of a deal in sight, the stage is being set for a potential work stoppage. The NHLPA has been pushing for changes to the revenue-sharing model, as well as increased player safety measures, but the owners have been resistant to making significant concessions. As the clock ticks down, fans are left wondering if they'll be able to catch their favorite teams in action this fall.
