The OP shared how their boss’ rant had completely demotivated and disheartened the team that was left. So much so that another worker then quit a mere two hours after this happened! Unfortunately, the OP deleted their Reddit account, so we were unable to reach out to them to hear more about what happened.
There probably isn’t a job in the world where shouting at someone for real or imagined faults is going to boost morale. Emotional rants will only ever make things worse. It’s an indication of low emotional intelligence. They show that the boss isn’t in control of the situation, doesn’t want to take responsibility, and would rather focus on finding someone to blame than focus on solving the real issues.
And though it can be a challenge, managers have a wide range of strategies available to them. In essence, you want to entice your employees to stay by providing them with good conditions and rewarding them for their efforts and results. Having a loyal team backing you up is going to be miles better for your profits than doing exit talks with staff and then onboarding fresh faces every couple of weeks.
Whatever the case might be, managers are under a ton of pressure to perform. And they have their limits, too. Overstressed, burned out, overworked, and demotivated—that can be your boss, too, not just you. So managing stress becomes a constant challenge.
