Banco del Estado de Chile, or BancoEstado, has elevated to the Supreme Court its complaint on the Labor Directorate's decision on the required minimum banking services in case of a strike, Pulso reported.

The move comes after the country's Court of Appeals affirmed the decision of the labor courts saying they are not competent to rule on the matter.

Several banks have already taken their complaints to the top court over the issue, the report said. Meanwhile, the Supreme Court has already asked the Court of Appeals last week to send a report providing background on the case within eight days.

The Labor Directorate previously ruled to require 1,173 employees to work and 118 of all 398 BancoEstado branches to be open during strikes. This is equivalent to 11% of BancoEstado's workforce, but the bank had requested 16% of the staffing to be available in these circumstances.
