The Histadrut labor federation instructed religious council workers on Tuesday to step up their three day-long strike and stop burying the dead during day time.

The decision to hold only night time burial services will affect mainly peripheral communities where the Hevre Kadisha burial society operates. In the three major cities of Tel Aviv, Jerusalem and Haifa, where burials are carried out by private companies, no disruption are expected.

The head of the Histadrut labor federation's department for religious council workers, Shlomo Stern, said that the strike was declared after delay in the payment of wages of some 230 council workers in 17 communities across the country.

"Due to the delay in the payment of your salaries, you might enter the new year and holidays without being paid," Stern told religious council workers in a letter.
