Office Manager tries to bully me into giving money for a present for our millionaire boss

The office manager is your typical social butterfly who loves to gossip and suck up to the boss at any opportunity she gets. I’m paid so poorly but a jobs a job to make ends meet for my family. I don’t have anything extra in my budget for myself or my kids let alone to put towards a gift for my already rich boss. I hate this toxic workplace 🥲
