I spent 15 years working nights. 3 x 12 hour shifts (which was the best way to work IMO) and 4 x 10.

I’ve been working 5 x 8 hour days for 4 years or so now and I guess I have adjusted some what but I still fucking hate it. 5 day working week is the absolute worst. The only saving grace I have now is my current job doesn’t care when I start / finish as long as I complete my 8 hours so I end up going in at 4am so I can finish at 12 and actually have some day time to do other things.

Actual 9 to 5 is possibly the worst way to work imo
