Elsevier is so vast, the actual work experience depends largely on the division. By and large, the employees and coworkers are great, intelligent hard workers. Much of the work is very intellectually stimulating. But workloads are highly variable depending on the position, some of which require many extra hours, salary is average to poor, and the benefits, with the exception of retirement (which is decent), are sub-par, particularly insurance, and are periodically down-graded to save the company money. Inconsistent work from home/remote and other policies, so you may be in luck, or not.
Performance evaluation process is incredibly painful, and managers scores are altered to conform to an average curve, so yearly salary increases are incremental. Opportunities for advancement depend on the position, but are largely for show or are lateral moves to try to reduce the relatively low employee retention rate of many divisions. Local management's hands are often tied, and corporate policies often overrule local management's wishes, particularly if it involves money.
