After vestment, he would receive two separate pension checks. Really the only thing he would gain by taking the job before his five year mark would be the vacation time he has earned. But, as soon as he takes the FT job his seniority date will change to his FT employment date. So, for instance he was hired in July for PT and gets a FT job in February, he/she will actually lose that time as far as seniority purposes go. The time served he will not lose, but his seniority time will be moved as far as vacation goes. It's almost as if the time between July and February was lost forever except for building seniority if layoffs were to occur.
me off when I was expecting my extra week at my fifteenth year and I had to wait a few more months until my FT hire date.
