Work problems

I am having problems at work.

Since March 2021, we have two new colleagues: K. who is 32 years old and C. who is 21 years old. It’s about K. I have noticed that K is a very dominant person and likes to stick to the office chair, she has drawn other colleagues into this. K had two colleagues who do all her chores so she can remain seated. I have reported this to the practice manager and they haven’t done anything about it. I was told not to get involved and to let it go. 

K was frustrated that people in the office moved stuff around instead of cleaning it up. When I heard this I was so angry, I called the practice manager the next day. I have already spoken about this during meetings and via Whatsapp for the past half year. I told K that it was a shame she didn’t come and talk to me, she told me that I also make mistakes and that I knew about this. We work in a veterinary practice that used to be a farm, so it has to be cleaned properly. 

I have been thinking about quitting, but there are rumors going around that K might quit, so I’ll wait and see. I’ve had a difficult year because my father passed away in 2021. Six months after my fathers passing my boss sadly passed away. During the holidays in December, a few acquaintances suddenly passed away, which was also difficult for me. Due to corona I have to work from home, I have noticed that I get sick more often.
