There are many misconceptions about offer letters. However, before you read this post, please be aware that this is not intended to be legal advice. However, I want you to know what an offer letter is and is not.
Up until about 15 years ago, some of my candidates got offer letters, some did not. It made no difference. Today, it is a matter of course. In fact, most of my candidates will not resign from their existing company until they receive an offer letter. They are correct to wait for the letter. However, even if they have one and it has been signed by both parties, it is not a contract of employment. An offer letter merely spells out a company’s intention to hire, but it is not a guaranty of employment and it is not a contract.
