They use a system called standard deviation. So they time every phone, email and chat transaction. Offline task or timed executable. They remove the outliers, so if a call that normally takes 10 minutes shows up as taking more than an hour, for example if you're escalating a complaint, then it gets removed from your performance. Provided you let a TL know and they check it's a genuine long transaction.
However, once they're removed, they find the average of all interactions of that type for the whole service area and the average of all your own interactions and you're marked within 3 steps of deviation from plus to minus. If it's minus, then you're really really fast. If it's plus, you're taking too long.
Since COVID finished we've noticed the average of all tasks has gone up significantly. For example a simple blue badge enquiry has gone from 3 minutes to about 7. All staff are fully trained, consolidated and they keep doing refreshers to make sure that you are more than competent. They grade you from 4 - 6 depending on your service level in our role and nearly everyone is on 6. Most staff members are above 1.5 positive on their interactions. We've all been given monitors, laptops with £800, keyboards, mice etc. so the equipment is fine. The internal network always asks us to do speed tests to identify who has slower connections but even then, were not doing anything that heavy that the work load or slow connection would slow it down. The processes and tools haven't changed. We didn't stop working throughout lock down.
There is so explanation as to why people are being so slow and folk aren't offering up and excusable reasons. They're taking too long on calls by having personal chats and not doing their job. They're taking their time on emails and chats because they're isn't a TL on duty around and Real Time can't watch 2500 employees at once when there's only 7 of them. The honest truth is that people are taking the piss. They are taking the piss and being caught out by posting on Facebook during work when not on break or lunch. They're on gaming services such as Xbox live etc. They're afk when they have no reason to be. They're staying in wrap for nearly twice as long to send and check messages on their phones.
Sorry if you don't like it, but it's true. Productivity is way down.
