Pros
Nice bunch of people doing the technical work (though many are unhappy and will no doubt start leaving). Used to be a great culture.
Cons
WSP bought the company I worked for (Opus) and it has been a downhill slide since then. It started with little changes (all pot plants removed nationwide, no more free newspaper for staff to read at lunchtime) that then progressed to changing the company management structure (going from a relatively flat structure to bringing in numerous management levels) and now they're making numerous policy changes that make doing our job more difficult and make employees feel like numbers, not people. The new management structure introduced several levels of middle management that are all ineffective and powerless. Technical staff are treated with little respect and policy changes have left us totally disempowered. Graduates are offered good training opportunities but staff above graduate level are offered nothing. The upper management is full of sycophants who constantly "slap each other on the back" for what a great job they're doing but don't acknowledge the contribution of technical staff. Numerous staff within the company were forced to take pay cuts due to Covid-19 and the upper management were very keen to inform us of the (tiny) pay cuts they also took, but they've not been very upfront about the significant bonuses many have since been paid. WSP is very quick to jump on the bandwagon when it comes to the latest trendy cause (mental health awareness, lgbt issues, diversity awareness etc) but they only pay lip service to it - they'll happily "manage out" staff with mental health issues if they're seen as a financial liability to the company. I felt very loyal to Opus as it was a great place to work - I feel no loyalty to WSP whatsoever.
