Vantaggi
I was with TMP for many years, and there was good reason for that. It is a flat organization, which means I had access to everyone I needed (across teams and functions and levels) to do my job well. This takes a good deal of initiative though, as nothing here (or anywhere for that matter) is handed to you on a silver platter. I grew a ton over the years and learned a great deal. Benefits were good, work was challenging and the people were great. TMP treated me very, very well and I loved working for them. When in the "right" office, the company is a fun and engaging place to work too - lots of outings, volunteer days, parties/celebrations, silly gatherings just for fun etc. Not all offices are like this, but great community in most of them!
Svantaggi
Managers don't seem all that well trained, and seem to be left to sink or swim with little support or training - which really impacts team synergies and trust. This is really unfortunate, b/c the company is filled with smart and motivated employees. Processes and systems can be disorganized and sometimes it took quite a while to sort through this - which is tough when you're on the front line with a client. I also would have loved more transparency from the "top" down - about the business, changes in benefits, company priorities etc.
