There’s a reason this is happening in Europe, and I have no doubt you’d find the same thing in the US. Our Employee Assistance programs try to help the individual when it’s the system that is the problem. You can’t solve the problem if you don’t identify it.
I’ve mentioned before that in some of the worst of my mental health struggles, I had a manager who helped me manage the process and was incredibly supportive of me doing what I needed to do, and I later had a manager who made the entire thing awkward and unbearable for me. This was at the same company. Nothing about the rules or the program changed, but my manager did. That made all the difference between me staying and being productive and walking out the door.
Could you do something for me? The next time you try to schedule a thirty-minute meeting with someone and see a thirty-minute break between long stretches of committed time, leave that time for them. Find a different time, if possible. Or go even further and commit to finding a time not immediately before or after another meeting. Let people have a few minutes. It’s good for all of our mental health.
