I have a co-worker that always uses "I'm too old" as an excuse.

You're 33. You're just a lazy piece of shit that doesn't take care of his body.

Fuck you, do work.

Meeting with a co-worker who is supposed to do a code analysis on a large legacy project. Actually, HER project - she inherited it already years ago, and the original devs aren't in the company anymore.

Her: customer is asking this and that analysis.
Me: easily two weeks.
Her: but who will do that?
Me: you of course.
Her: but I don't know most of the code.
Me: me neither.
Her: and I don't know the protocols.
Me: google them. I'd have to do the same.

Really, I told her to google shit, which I consider as quite a slap for a co-worker. Basically, she tried to offload a complex analysis because she just wants the low effort parts of the job.

Won't happen. DO YOUR FUCKING JOB!

The worst co worker I had is actually pretty recent. He joined a well integrated team on what was basically a legacy project. He sounded like a good developer and seemed to know his stuff but it took him ages to push out fixes/features. They were always massively over-engineered, poorly named, partially tested and what documentation he did write still managed to bitch about how poor the project was structured.

He spent most of his time bitching about the general shitty nature of the project (he wasn't wrong) and the lack of interest from other Devs.

He was so unpleasant in interpersonal communication that by the end no one would work with him.

In his last team meeting he basically said he was glad to be going and that we were all lazy, disinterested and shouldn't consider ourselves his peers. The equivalent of storming out of a party after setting the couch on fire and shitting in the sink.

We've since removed all his overcomplicated, not standard, unmaintainable code.

Management suddenly decide to push for an early go-live for a product being worked on by another dev team in the company. As a result we are pulled in to help and get extra tasks loaded onto our sprint.
My co-worker pulled an all nighter to get the extra work done.
I emailed the project manager to remove items from my sprint to make space for the new work.

Am I lazy, or smart?
