An employee who has put in his service for a period of 240 days in fifth year will be deemed to have continued in the service for 1 year. Mettus Beardsell Ltd., Madrs Vs. RLC(C) 1998 LLR 1072(Mad)
To be eligible for gratuity, you must complete 5 years continuous service. 6 months of a year can be counted as one year. If you have completed 4 years and 7 months in service, you will get the gratuity.
A judgment of Supreme Court rendered under the provisions of the Industrial Dispute Act in Surendra Kumar Verma vs. Central Govt. Industrial Tribunal,[(1980) (4) S.C.C.433)], it is enough that an employee has a service of 240 days in the preceding 12 months and it is not necessary that he should have completed one whole year’s service. As the definition of continuous service in Industrial Dispute Act and Payment of Gratuity Act are synonymous, the same principal can be adopted under the act also and hence an employee rendering service of 4 year 10months 11days is considered to have completed 5 years continuous service under sec.4(2) and thereby is eligible for gratuity."
Continuous service means uninterrupted service. But, it does include the interruption due to, leave, sickness or accident. The strike, lay-off, or a lockout is also not considered as interruption. Indeed, any interruption which is not due to the fault of the employee, would not be counted.
You can issue a legal notice to the employer citing the relevant laws on this and demand for gratuity and can follow it up through court if the management is not responding properly.
