Try that phrase again and remove the "un". You are deserving.
Or this way: You. Are. Deserving.
When I work with companies with unhealthy cultures I often find people who have been beaten down over time and feel like their best their ideas have been killed by the system. When this happens often enough, people simply lose faith in who they are, what they can do and why they come to work each day.
Management's job isn't to beat people into submission. It's to lead them with a focus on a greater good, a bigger goal that will require everyone on the team bringing their best ideas every day. You deserve to have your best ideas heard.
You deserve to be recognized for contributing to the greater good. You deserve to know you have value in your role every day and that the company you're in is better because you are there.
You. Are. Deserving.
It's tough out there. Making a difference takes a lot of work. We need you to bring all the goodness that makes you uniquely you. And you deserve a company that will celebrate you. You are deserving.
