Pros

It's easy work, and people in your group are really great and supportive. I guess when times get rough, you stick together.

Cons

People are leaving, and they continue to ignore issues by creating a high employee turnover. We are piled on top of one another- there is simply not enough room for all of the employees we have. Yet the sample load continues to increase, and they will not stop hiring people. There are many days where I have had to stand up and eat lunch. Those of us who work in the laboratory, despite being highly educated, are treated like we are disposable. Our ideas are ignored. We are warm bodies and mindless drones to them. If you don't like it, you will be replaced by a bright eyed, bushy tailed recent college graduate for half the price. It has been made quite clear where we stand. The directors call everyone- PhD or master's degree- "the techs". I once asked for the opportunity to move into a new role, and the director I spoke with told me she didn't think I'd understand the job tasks. At Sema4, you're a line cook with no future. You will not move up here unless you are white or married to someone high up. Lisa Edelmann is truly one of the most vile and aggressive individuals I have ever been around. She has created a toxic work culture, and now everyone who has worked with her for a long time and endured her abuse are now just as abusive. She talks down to people and makes them cry. HR consists of 3 people who rarely answer emails. Awful benefits. No education support.

Where good grads go to die

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.

Pros

Some nice people, but that's a select handful if you're lucky enough to meet with them

Cons

+Very egotistical leadership focused on old glories and Sinai brand, rather than present wins +Poor benefits, low pay -- and deliberate undervaluation of employee skills and potential +Very much a good old boys club vibe at the top -- the only way to move up here is to know somebody from a previous job. NO real opportunity to grow +Call themselves a start-up, but the culture, like the executives, is IBMish -- most hierarchical place
