A new wave of strikes has hit this communist nation, and thousands of shoe workers marched on Parliament Tuesday in heavy rain to protest the plummeting living standards.

A triple cordon of police officers guarded the doors of the Parliament building as about 3,000 shoe workers, mostly female, chanted: "You are afraid of women, shame on you!" and "Thieves, thieves!"At the Labin coal pits, 148 miles southwest of Zagreb, about 1,000 miners stopped working Monday to demand payment of a bonus for having fulfilled the annual production quota one month ahead of schedule, Belgrade newspapers reported.

Also Monday, several hundred workers at the Bor copper mines, about 90 miles southwest of Belgrade, staged a brief work stoppage for the same reason as the Labin miners, newspapers reported.

In Belgrade, a total of about 7,000 shoe workers went on strike Tuesday.
