I was in therapy the entire time I was in my last job (9 years in therapy, 8 in the job) and it made a lot of difference. My coworkers, bosses, everyone knew I was in therapy and we sometimes made jokes and references to it and good coworker friends and I would talk about it and me and whether I was better/worse, etc. I was having trouble relating to my senile stepmother at the time and the good friend coworker had a difficult mother and I was able to "copy" her behavior and tone on the phone, sorts of ways she communicated with her mother successfully so my behavior became much better. I would not have been able to do that if I had not learn better communication skills in therapy. I was able to get some good insight about work problems discussing them with my therapist and was otherwise able to use work and therapy to improve on the other.
