When they did the open space with free snacks I told them I was never coming into the office again. I pointed out that I got sick roughly 3 times a year from just being forced to spend time in that hazardous office. And I then I sealed it by telling them that they will get 2 extra hours of work out of me each day plus all the CO2 I wouldnt be pumping into the atmosphere each day when I drive there on the perilous freeways with all the other pissed off people on the road. And they bought it. This was 2012. Ffw to 2019, I still work at home for the same company. I never get sick, I dont have to deal with any of the toxic culture stuff at work, and I buy and consume my own snacks, the ones I want to eat. I agree, it's a circus and it's a lot easier to manage from a distance.
Hate open offices too, but take some Vitamin D3 if you getting sick all the time. Exposure to pathogens is what exercises the immune system and is a necessary evil.
