Step 1: Understanding the Labour Law Context.
The Industrial Disputes Act provides the framework for resolving disputes between employers and workmen. Under the Act, a workman can file an application in the Labour Court or Tribunal against issues like dismissal, discharge, retrenchment, or termination of service, among other things.
Step 2: Explanation of the options.
- (a) Dismissal, discharge and retrenchment: This is not the full scope, as "otherwise termination of service" is also included in the provision.
- (b) Dismissal, discharge, retrenchment or otherwise termination of service: This is the correct answer, as it encompasses all possible causes of disputes.
- (c) Discharge simpliciter exclusively: This is incorrect as the provision is broader than just discharge.
- (d) Dismissal and retrenchment exclusively: This is also incorrect, as the provision covers a wider range of terminations.
Step 3: Conclusion.
Thus, the correct answer is (b) Dismissal, discharge, retrenchment or otherwise termination of service.
