Even in the hypothetical case later presented, the eligibility for gratuity of the employee on account of his resignation on 02-01-2014 is not in dispute as he was on the rolls of employment of the employer ever since his joining on 01-01-2009, i.e., for 5 years. Now, the pertinent question, therefore, is whether he is entitled to gratuity for all these 5 years or only for the first consecutive 4 years since the number of days he actually worked in the 5th year is only 170 days due to Leave Without Pay. Will the Questioner be kind enough to read once again in its entirety Section 2-A of the Payment of Gratuity Act, 1972, which defines "continuous service" for the purposes of the Act?
Understanding Continuous Service Under the Payment of Gratuity Act
For the purpose of entitlement of an employee to gratuity for a period, sub-section (1) of Section 2A creates a legal fiction in respect of the meaning of the term "continuous service" comprehended commonly out of the actual meaning the phrase conveys, and sub-section (2) explains the fiction thus created. The fiction created by the Statute under sub-section (1) of Section 2A is "Uninterrupted Service" inclusive of "certain interruptions" viz., (1) sickness, (2) accident, (3) leave, (4) authorized absence from duty without leave as per standing orders, rules, or regulations in force, (5) lay-off, and (6) strike or a lock-out or cessation of work not due to any fault of the employee. Sub-section (2) of Section 2A explains the fiction with reference to the number of days the employee concerned actually worked in the contingent of the impossibility of notional reckoning of continuous service as stated previously. Here again, by the explanatory note to the sub-section, the absence of the employee due to permissible lay-off, authorized leave with full wages, temporary disablement caused by any employment accident and in the case of a female, permissible maternity leave are to be notionally included in the actual number of days worked.
Clarifying the Confusion
Seems a bit confusing? Actually not so, if one makes an isolated reading of sub-section (1) at first for the purpose of determining continuous service for gratuity and then only proceeds further conjunctively with sub-section (2) only in the case of impossibility. In other words, in a period, if the employee's service remains uninterrupted inclusive of the specific interruptions mentioned therein in sub-section (1) of Section 2A, he is straight away entitled to gratuity irrespective of the days he actually worked. Otherwise, you have to be on the lookout for the minimum number of days he actually worked in the light of the explanation to sub-section (2) of Section 2A to determine his entitlement.
Conclusion on Gratuity Entitlement
Coming to your question, if the Leave Without Pay is permitted in the rules/regulations/standing orders of your establishment, he is entitled to gratuity for the 5th year though his actual number of working days is only 170. Otherwise, he is not entitled to gratuity only in respect of that year.
