A or B? Both?

I have now been working at my company for four and a half months...and have been dealing with a co-worker that has a very strong Type A personality.

"The theory describes a Type A individual as ambitious, aggressive, business-like, controlling, highly competitive, impatient, preoccupied with his or her status, time-conscious, and tightly-wound. People with Type A personalities are often high-achieving "workaholics" who multi-task, push themselves with deadlines, and hate both delays and ambivalence." 

Well co-worker "L" has the characteristics in bold.  I, however, happen to also be more of a Type A than B.  So, you can see where this is going.

L came back to work today after being on vacation for the past 10 days.  L is the 'Office Manager'  This past Thursday was the end of the YEAR, kind of a big deal in the accounting world.  Once I left the office on Thursday, the accountant was going to close out the year.  Pressure's on new girl!! Yikes!

The last day before she left, I asked if there was anything I needed to be aware of or watch for--"nope, I have everything taken care of."  But, when she comes back all I heard was 'Did you do this?' 'Why was this done?' 'Did you document that?' 'Did you mail this?' all morning.  And my answer--I wasn't aware!

Did I get one single THANK YOU for fixing your invoicing you weren't supposed to do, or the check you wrote to the wrong company for our company's insurance policy for the entire year?  Nope, not once.

Is it normal to not get any credit for going out of your way to fix things others messed up?  I really try to think positive in the office, however everyone is so negative as L rubs off on them.  Nobody wants to stand up to her, and they let her call the shots.  I have never had a job where the employee tells the boss whats going to happen.  Maybe I have the wrong job? :)

Note to self: Type A personalities do not work well with other Type A personalities.
