Yes they may have to do a 5 hour day instead of a 4 hour 55 minute day.
Collecting bags and emptying a wheelie bin takes more than double the time for a wheelie bin alone. I know you weren't being too serious but multiply those seconds by even a small percentage of the hundreds of households per round who want an extra bag or two collected and it gets to be rather more than five minutes.
I retired a few years ago so my working knowledge is a bit out of date, but the crews then were working as many hours as it took them to do their round, which was often a lot longer than most people's working day, plus they were being paid peanuts by whatever cheapskate contractor won the contract. Once they finished their round, they had anything up to an hour's drive to the waste centre (most of the local tips closed years ago), then back to the depot before knocking off.
I had to go once and give a talk on the local radio about a public heath alert, which involved driving 15 miles to the studio on country roads through deep snow. I got there on time, just, and was dumped straight on air. The conversation went something like this.
"This morning we have Rezillo, from Coconutinthecoconutshy Council to talk to us about why we're all going to die from whatever scare is currently in the Daily Mail. Rezillo, you've had quite a drive-in this morning?"
"Yes, a lot of drifting snow but I got through the back lanes with a little care, thanks"
"Well, that's good to hear. So you got through in your car but your council's refuse lorries remain in the depot and are not going out. What have you got to say about that?"
What I felt like saying and what I actually said were poles apart.
