I am a tech lead.
I am not leading this guy, because he is in another project. But I take care of some frameworks, and I am a little on the top of his work.
Anyways, the problem is this guy keeps having sick days. When he is working, he performs well, but sometimes, he just feels he does not want to work.
He then send a message to the team, saying that he is sick. I know it is not true, because I saw him the other "sick" day drinking a beer, and some fellows told me he used to do that in another company as well. Other people have also done this calling it the "Lazy-day"
We live and work in Germany. Is there a way of firing him?
He is coming to be part of my team soon, what should I do as his team lead?
