Well sickness and stress and mental health issues, have increased in the last year.
Losing a loved one is devastating. Losing them during a pandemic with all the restrictions must be even worse. When my uncle died, we could get together and support eachother. I had a gaping hole. I couldn't understand how the worl was still turning without him. Having to go through that without my family, must be horrendous.
But, my personal opinion is that the 'well being in the work place' doesn't really work. Because usually, it doesn't translate into the real work place. Actually things that could help aren't put in place. It also puts people in a weird position, where if a colleague is having a bad day, they feel they have to spot if its MH issues or a bad day.
They don't want to try and cheer someone along, incase it's more serious. The low level everyday support, reduces, because people don't want to be seen as trying to make light of mental issues and been seen as one of those people that is telling someone who is depressed 'ah come on it will be ok'. But sometimes people aren't depressed and that's what they need.
Well being in the work place is usually a tick box exercise so employers can get 'investors in people' or similar awards. It doesn't really help or actually work to support the colleagues.
One of the places I worked that was the biggest 'we care about you' was just awful. I opened grievance about bullying I recieved from a senior manager' HR and my manager met with me. At the next meeting HR didn't come. My manager came and told me the HR person wasn't available, so he brought someone else. The person, he brought was the best friend of the senior manager the grievance against. The senior manager was this womans children god mothers.
I walked out that day and never returned. It was made clear, they didn't give a shit. And were doing what they could to try and shut me up. How do you talk freely, in a setting that's meant to confidential, when you know someone on the room will tell the person.
So no, I don't think it works. But not for the reasons you think. Its possible that the emphasis on supporting mental health issues makes people, more comfortable about being open about it. And of course, some people will see it as a way to get time off with you not being able to really do much about it. But that group will be fairly small.
