Pros

Team is lovely and great interactions. I love the people I work with.

Cons

Too many reorganizations and restructuring initiatives. Company culture appears to be moving towards less collaborative and more of a single decision-maker mindset.

Toxic culture and lack of respect for employees

Pros

Pay is decent, but that’s about it.

Cons

They do not follow any of the US holidays or care about US employees at all. Toxic work culture with no work life balance. No one respects boundaries. No RSUs. No support for teams. Probably the worst company I’ve worked for where I felt like simply a number and not a valued employee.

Thank you for taking the time to share this feedback. The concerns you raise about respect, boundaries and the way people are treated are serious and not in line with the standards we expect across our U.S. organization. We also understand that local practices, including holiday calendars and benefits, have a direct impact on employees’ day-to-day experience. While offerings can vary by role and business, we want decisions and communication to be transparent and teams to feel supported. If you are currently experiencing inappropriate behavior or a work environment that feels unsafe or disrespectful, we strongly encourage you to speak with HR or use our SpeakUp channels so the matter can be reviewed and addressed. Your input is also important in our Employee Engagement Survey, which helps identify where leadership and culture need focused improvement.
