Cons: no loyalty here. they will fill you with false hope.
There was a time when, if you had asked me to recommend a good temp agency, I would have recommended Monarch without hesitation. I worked for them several years ago and really loved everything about them. Then I went to school, and when I got out, they gave me the runaround when it came time to place me for a new position. They had blithely forgotten the dedicated employee I had been and were probably seething over my audacity to leave them in order to return to school to better myself. The jobs they post on their site are bogus. Do yourself a favor and apply for a "real" job outright.
