I have read several stories on here recently about people taking the brave step of resigning from a toxic employer and moving on to better opportunities. That's fantastic! However, I would like to offer one piece of advice:
DO NOT DISCLOSE/SHARE/REVEAL ANY INFORMATION ABOUT YOUR NEW JOB TO YOUR CURRENT EMPLOYER WHEN YOU RESIGN!
Honestly, I thought this was common sense, but apparently, it's not. Even if your former employer has been good or even great to you, it's essential not to reveal any details about your new position, your new employer, or any information related to your next opportunity. I've come across too many stories on here (whether true or not) about former employers sabotaging new job opportunities.
If they inquire, consider lying. They often do the same to you. You can tell them you're taking a break from work, caring for a sick family member, or any lie that makes you feel comfortable.
If you can't bring yourself to lie, you can respond with something like, “I cannot disclose that information at this time, and I won't be able to provide further details.” Use your own words and tone, of course.
Regardless of how good your current employer has been, do not place your trust in them. To them, you are a number and a business expense. They make more money from your labor than they pay you in wages. Avoid sharing personal information about your future plans with your current management, and I would even recommend not sharing that information with your coworkers.
For an extra layer of security, consider delaying updating your LinkedIn profile until you're six months into your new job, ensuring you're already established in your new role.
Always remember, these companies and managers are not your friends. You are a business expense to them. Don't take it personally. Think of yourself as a free agent in the world of sports—you make the moves that best serve you, regardless of how inconvenient it may be for your previous organization.
