NFL officials' lockout at a glance

The NFL told the NFL Referees Association on June 3 that the officials would be locked out because of an inability to reach agreement on a new collective bargaining agreement. Replacement officials were hired and worked all preseason games and the first two weeks of the regular season. No new negotiations are scheduled.

The league's latest offer would increase yearly average compensation for the locked-out officials from $149,000 in 2011 to more than $189,000 by 2018. The NFL also offered a new retirement plan.

The NFLRA wants the pension plan to remain in place for all current members, and not have a 401k program replace it. The union also opposes the NFL's request to add three crews -- 21 officials in all -- because the league is essentially asking officials to take a pay cut by not substantially increasing the total pool of money available for them.

The NFL recently said in a memo that there was a gap of $4 million per year in the salaries it was offering and what the officials wanted.
