Assuming you’re in the US, no one was banning you from traveling or gathering with loved ones. There was nothing close to an actual lockdown that was implemented in the US. Losing income is a different story. Coming in to work and endangering other people’s health without their consent is not acceptable. Not to mention that most antivaxxers are antimaskers as well, which made it worse. If you purposely do not take the necessary precautions to keep other people around you safe, then you shouldn’t be working there. That applies to anything, not just Covid.
