She would be eligible for gratuity unless there is a break in service between 1/6/ 2007 to Decmber 2013.
The candidate rejoined in February-2010 means the employee is having service of two terms i.e. 1/6/2007 to November-2009 and February 2010 to December-2013. Each tenure is less than five years for which she is not eligible. But combined together is more than five years, if not break in service.
You advice your friend to make an application (if there is no break in service) in Form I. If not considered by herr employer lodged a comaplint with local labour authority.
