Psychiatric impairment justifies late appeal filing even without medical work exemption.

The Supreme Court quashed the lower court's dismissal of the employee's claim to restore working conditions. The employee filed an appeal two days past the statutory seven-day deadline due to transient psychiatric disturbances requiring medication, despite not being granted a medical work exemption. The court held that the short appeal period must be interpreted liberally to protect workers from unintended negative consequences, and the minor delay was excused by the lack of fault.
