So, reneging on an offer is not the most desirable thing to have happen for an employer. Like all commitments, you have to think through the ramifications for both your personal brand and the company’s perception to your decision. Nevertheless, it is still a decision that you have to make for yourself. So, definitely think through everything very carefully and weigh your pros and cons. If you do decide to renege be honest, apologetic, and communicate it the earliest you are able to make a decision so they can move forward with trying to fill the role again.
In the future, the best way to prevent the possibility of having to renege on an offer is to always openly communicate with the employer your ideal work environment and if needed, ask for an extension to the offer. Work life balance is important, so definitely be true to yourself in terms of your needs when making an employment decision. Best of luck!
