The following are not really cons, just reactions to business climate. Currently undergoing integration of many recent acquisitions, ENSR, RETEC, Earthtech, and others which has temporary challenges - but going pretty good. If you are in an office that is moving and changing the career advancement can be rapid, but if in a smaller or less active office it can seem slow. Recent economics has meant a few layoffs, and more emphasis on being billable. Since AECOM is a publically traded company, managers seem to have more pressure to hit home runs at the end of each month and quarter as compared to the legacy companies – just seems more aggressive and less forgiving than before acquisitions (less fun). Cash bonuses can seem small and discretionary.
