Hello All , I have left my Employer where i worked for 6 years in November 2019 . And i joined another company in December 2019. My previous employer did not issue me C4 form . I am still employed by my new Employer . So do i really need C4 form of my old employer in future ? What exactly is the need of old C4 forms from previous employers ? Or do we only need it for current employer or latest employer ?
