Defining an entire company as being toxic may sound harsh so let's reframe it.
Start by asking yourself, what are the dangerous or destructive things (culture norms) inside of your or a company? For example working long hours as a norm. Or never taking time off. Or when you take time off you are still available and responding to emails, texts, phone calls. Perhaps it's zoom calls with videos not on. Perhaps you have hybrid work but everyone is a on a different schedule so what is the point of going into an empty office. The list goes on. The point is ask yourself where you may have some dangerous norms that are keeping you, your team, your organization from being a highly performing team due to these 'destructive' things, 'toxic' things. How can you make some shifts that will ultimately increase engagement, retention and better attract new talent?
