Pros

Possibility of remote work 100%

Cons

An enormous amount of duties (normally covered by 2- 3 people) Extreme micro-management Changing KPIs during the year for your annual goals Massive restructuring (people leaving/getting fired - usually you hear about it after they leave) Management works 24/7 and expects you to deliver without prioritisation - you just have to deliver 100% of what they said they expect (no space for discussion, no possibility of realistic assessment of what brings value, no dialogue)

Pros

Decent pay assuming your position isn’t eliminated part of restructuring. Used to be a decent company to work for under VWR. Between previous and current management that has all changed for the worse under Avantor.

Cons

Company in serious decline. New CEO who has been his role going on a year has failed to address and fix declining revenues and shrinking margins. The only actions taken has been to offset falling revenues and margins with serious cost cutting initiatives recently. No raises for employees, multiple rounds of layoffs with significant headcount reductions, travel bans for employees all while upper management goes on a company world tour to showcase site visits on LinkedIn. Years of failed M&A deals when capital should’ve been spent investing in outdated company sites, talent and other initiatives to help keep up with competitors who are much better positioned and experiencing growth compared to Avantor’s decline. I would give the current state of the company a 0 if this site allowed for such a rating. Moral for employees is at an all time low and i think with all that is going on nothing will change for the better anytime soon. Most employees feel if they do not hit their numbers which are unrealistic to begin with they will be let go of as they’ve even seen top performers pushed out to cut costs.
