Your Boss Broke A Promise. Here’s What You Should Do Now.
Put every agreement in writing
An agreement doesn’t have to be a signed contract, just an exchange acknowledging that both of you understand the terms. You can do this easily by sending a casual e-mail confirming a promise that was made.
Example: “Dear Betty Boop, thanks for informing me that I’ll be promoted after learning this skill. I’m excited to further my career with our company!” Here you’re putting the agreement in a note that you can pull up later if you need to contest the broken promise.
