The strike at Boeing by 33,000 members of the International Association of Machinists union, which reaches its seventh day today, has already cost the company and workers $572 million, according to an estimate from Anderson Economic Group.

And the pace of losses will climb rapidly if there’s no settlement, as soon as the second week of the strike, said Patrick Anderson, the founder and president of the Michigan research firm, which has experience estimating the cost of economic disruptions like strikes.
