Pros
The support network established by fellow lab members to weather the storm of upper management; good coworkers (in general) are why many people still remain despite the endless workload
Cons
Management at Sema4 is really only interested in one thing - how many hours of unpaid overtime they can squeeze out of you. Work-life balance is non-existent for many lab techs, and it's painful to see once-happy people reduced to husks of their former selves. Even worse, your good work is rarely appreciated - it's only noticed if you make a mistake (which, given how overworked everyone is, will become more & more common). Once you are placed in a group, you will most likely remain in that group until you leave. There are no opportunities to learn any new skills beyond what your daily job requires; they don't mind if you languish under the monotony of repeating the same tasks every day. Sema4 is a place with a highly-educated workforce, but you wouldn't know it based on how condescending higher-ups are; several supervisors are so poisonous, it boggles the mind as to how they are still employed. Some are sympathetic to the existential dread facing lab techs every day, but can do nothing to stop it. Transparency is nil, and the reality in the lab seems far divorced from the reality of the sales team. Sample volume has doubled over the last year, but the amount of techs hasn't changed - if we aren't all working 7 days a week in the next year, I'd be surprised (that's if we're all still working there next year; the company is bleeding lab techs). Overall, there are not enough machines to handle the sample volume, there are not enough people, there is very little physical space for more machines or people. It's almost comical if it wasn't so tragic.
