We have a person on our team who is never available ( always offline, they joined 3 months before covid and they would show up at office after 10 AM and was out by 4 PM) . When I was coaching them in office, thir phone would constantly buzz and they couldn't wait for me to leave their cube so that they could get back to their phone. Never met any deadline and made so many mistakes ( after so much coaching) in the work that I had to fix. They would ping me on Fridays at 4 PM as they need urgent help to complete pre-scheduled tasks ( this is after being offline for most of the week and me telling them that they should plan enough buffer to deal with unexpected issues and still meet deadline). The performance was so bad that they had to be moved to do less impactful work and that was the end of my work with them. I have no idea what they do now ( I know what other team members are responsible for).
If this person survives the layoff, I will be applying outside even if I survive this layoff. There is no way a company can do well with this type of workers.
