To be honest it doesn’t feel like this is specific to testing. A lot of people just want to work their contracted hours, have a quiet time and then go home at 5pm to crack on with the stuff they want to do.
It’s a matter of perspective whether these people are ‘zombies’, or just follow the ‘work to live, not live to work’ mantra.
You’ll find these people in every profession, and it’s a frustration for sure, but I find it somewhat snobby to call them zombies just because their priorities are different from our own.
Most testers don’t spend their free time at meetups, conferences or reading testing blogs. Most probably don’t strive to break barriers or want to veer from how they’re told/taught to test. But that’s fine. Every person wants something different out of their job.
And let’s be honest here, our career progression would be much slower if these so-called ‘zombies’ didn’t exist. I know I wouldn’t have made the impact I have at the companies I’ve worked if all the other testers were preaching and ranting as much as I do!
