Industrial disputes: employers barred from worsening conditions or dismissing workers during proceedings without authority approval. When an industrial dispute is pending on matters not covered by a notice of change, an employer cannot worsen workers' conditions or discipline them for dispute-related misconduct without the authority's written permission. For actions unrelated to the dispute, employers may follow standing orders or contractual terms, but dismissals require payment of one month's wages and an application to the authority for approval. Recognised trade-union office-bearers designated as protected workers cannot be prejudiced during proceedings; rules fix recognition numbers and permit the Government to regulate distribution. The authority must ordinarily decide approval applications within three months, subject to extension.
