I'm currently on mat leave, which officially doesn't end until Jan '20 but I'd agreed with my current employer that I'd return to work in October (technically Sept, using my accrued holiday).
However I've now been offered a job at a local agency which will cut my commute from 1+ hr to 15min!
Question is, how do I give notice to my current employer? Do I need to call my manager? Or send a formal email?
I understand they may make me work my notice period (though hoping they won't). But not sure how to bite the bullet and tell them!!
