Summer Fridays that you plan to be off can be taken away to do work for some Managers who want to get ahead of jobs that are months from being completed.
They really don't get rid of bad employees fast enough. People get WAY too many chances before being let go. I was able to bounce around a few groups for a while doing barely any work and then started working from home most the time because commuting in to do no work was a waste of time.
Some terrible Managers who micromanage jobs and demand you work 24/7 because "the partner needs this!".
Too much focus on billed hours vs jobs getting done. Why should I get 50+ billed hours if I get my work done in 43? Why is it a negative I'm not killing myself to work more hours when I'm more efficient than the other people on a client?
