Let me see here, you found double standards at walgreens...SHOCKING!!!
Actually, the only thing shocking about this is that you seem to think it has anything to do with you being black or a woman. I hate to break it to you lady but there are double standards EVERYWHERE...don't even get me started on some of the ones at my store. Actually I won't post any details about my store because I want to keep my job for a while. (hint hint)
The fact is that most of these things happen because a manager is too lazy to enforce equitable standards. Other employees that get away with stuff while others are punished for the same things tend to do so because they have done something to garner some consideration from their manager. Often this is nothing more than showing up for work every day for a long time. Seniority is the most common excuse for what people get away with...you'd be surprised.
Also, I'd like to know what kinds of horrors the cashiers, photo techs and cosmetics folks at your store are subjected to. Of course, being the self-serving person you seem to be there is no mention of double standards that apply to them, though there most likely are several serious instances in a store that is run by a manager like yours. I don't see you even acknowledging this fact, meaning that you are either oblivous (and therefore part of the problem) or you only care about yourself. Honestly, I wouldn't be this offended if you hadn't tried to play the race/gender card, and your lack of concern for your subordinates tells me that you lack the moral fortitude to be a good manager. There are people in walgreens who have to put up with MUCH worse than what you claim to and they have no one sticking up for them.
And finally, to whom is your post directed? Do you think this site is owned by walgreens or something? Obtain a clue please. You make my comment in another post about clueless managers more valid than it should be.
