Pros

Not really applicable; maybe decent benefits

Cons

This position is not for college graduates; it is for someone looking for janitorial work. * Upper management (C-level executives) mandates changes in work schedules for employees without previously discussing them. * Pay is poor and does not meet the market average. * Management (C-level executives) spends more time trying to take negative Glassdoor postings down than they do on employee retention. * The work environment is not safe and does not meet OSHA or EPA standards, as the room used for dispensing harmful and volatile solvents does not have proper ventilation. * Most of the work in this position is janitorial work, so you will be mopping the floors, cleaning glassware, and taking out the trash daily. * Concerns brought to management (C-level executives) are ignored and shoved under the rug. * The position does not offer a good work-life balance. * No opportunity for upward movement in the company unless you brown-nose management (C-level executives) because their only concern is minimizing their costs. * Raises and bonuses are given on a bell curve, so in order for someone to get a larger raise, another person needs to receive a lower raise. * Biweekly meetings with direct supervisors (C-level executives) never happen, as supervisors are more concerned with their own personal agenda than managing their supervisees. * Management (C-level executives) uses a lot of smoke and mirrors and never gives employees straight answers regarding changes in the company.

Pros

Good benefits Paid time off Generous vacation time

Cons

Not much room for growth, every development I have been able to make with a degree has been entirely horizontal. There has been a hiring freeze for over a year now and it's not expected to lift anytime soon. Bonuses are low and pay has fallen below the cost of living. A mandatory return to office has been pushed on the entire workforce with little thought to how this effects employees who were initially hired fully remote. During covid the company was very good to it's employees, but that seems to have changed.

Pros

Your bills are getting paid.

Cons

"Suck it up" Culture. New President hired has encouraged a shift away from supporting employees. WFH being revoked. Office location is inconvenient. Very likely to be stuck in your position and denied growth opportunities.
