Ford lays off 600 workers at plant targeted by UAW strike

This is a most excellent place for technology news and articles.
It depends on the kind of strike. Workers that strike over a company's unfair labor practice are protected from permanent replacements. This is not that tho. While they are far apart, I don't think they can accuse the companies of refusing to negotiate.
Of course if the union wins the strike then no replacement.
