Pakistan Essential Services (Maintenance) Act, 1952
Summary
This 1952 law lets the government designate certain jobs as "essential services" and then restrict the freedom of people in those jobs to quit, strike, or move away, in the interest of defence, security, or supplies essential to the community. Section 3 lets the Federal Government declare, by Gazette notification, any employment beyond government employment itself (which is automatically covered) to be an essential service, but the declaration can only last six months at a time, though it is renewable.
Section 4 lets the government order employees in these essential jobs to stay within specified areas. Section 5 makes it an offence for a worker to disobey a lawful order, abandon their job or refuse to work without reasonable excuse, or leave a restricted area without consent; employers who dismiss such a worker or shut down a workplace to force them out without reasonable excuse also commit an offence. Two Explanations clarify that fear of danger is not a "reasonable excuse," and that even giving proper notice under an employment contract doesn't excuse abandoning essential work without the employer's consent.
Section 6 lets the government make rules regulating wages and conditions of service for these essential employments, and failing to comply with such rules or directions is also an offence.
Section 7 sets penalties: imprisonment for a term which may extend to one year plus a fine for anyone found guilty. Where the offender is a company, every director, manager, or officer can be held liable unless they prove the offence happened without their knowledge or that they exercised due diligence. Under Section 7(5), only a first-class Magistrate can try these offences, and cases can be tried summarily. Section 7A makes the Act override the Industrial Disputes Ordinance and other conflicting laws.
This is an old law from 1952, substantially amended over the decades (see the 1958, 1965, and 1978 amendments referenced in the footnotes), so anyone relying on it should check the current text, especially regarding which employments are currently declared "essential."
