The workload was unbearable. Most lawyers had north of 600 cases on their respective dockets from case sign up to final disbursement. The workload weighs down everyone, paralegal and lawyer alike. There's no possible way to keep up with everything they put on your plate, even if you were to work 14 hours a day 7 days per week. You barely have a life outside of work at this place if you simply want to stay afloat. In other words, they work you as though you were a partner - but they won't pay you even close to what they pay the partners.
The business is run to profit those at the top only. Clients are often unsatisfied because paralegals are trained to keep them away from the lawyers - so lawyers can be mediating and otherwise settling other cases (bringing in the money).
Lawyers and their paralegals are constantly demoralized with the workload. Only a handful of people were willing to speak out about the workload, but when they did, their concerns fell on the deaf ears at the top.
