I’ve been a guard 6 years now and on my patch the job has changed loads.
Give it another few years and it probably will look completely different still.
That being said the best bits of the job are being able to work without supervision, you just work within the boundaries they set and as long as nothing happens you can go months without even seeing a manager.
I must say though the worst bits are being unable to help people, very occasionally your in the position where you wish you could do more but your unable to, sometimes it’s of your own making because your not experienced or to pig headed to see the bigger picture.
On my route we have a lot of ticket issues and this wears thin, it’s difficult to keep doing the same thing and expecting different results. That being said managers always listen and it’s not a problem with a easy soloution.
I’ll be lying if I said nobody does it for the money but its what keeps people from leaving
