One of your best opportunities to voice displeasure with Trane is to leave a negative review on company review sites like Glassdoor or Indeed before you sign any severance agreement (or even after, if it allows). There is power in numbers, and it's time for the company to feel some pain related to its recent poor decisions.
This is an opportunity for you to warn other good people and hard workers about this company and its executive leadership team. Nothing brings about change like public pressure and a dose of shame. You can make a difference!
