I missed mandatory managerial meeting at Popeyes chicken and they want to fire me. I've never had a feeble or written warning

Unfortunately you can get fired for missing the meeting notwithstanding your good employment record. The termination would be on a "without cause" basis and you would be entitled to a severance package proportional with your years of service, age, position, and level of compensation. Should you receive a termination letter I encourage you to contact us at the number below to discuss your entitlements and options further.
