Okay, I know that the hot weather makes me grumpy. But, what is it with people? You work hard, do more than you have to do (alot more), help wherever and whenever your help is needed. Did I mention covering four positions one day last week? Then, something goes not as planned and someone quickly tries to make it your fault (it wasn't my fault by the way), and gets all surprised, when (surprise!) you tell them that a) it was their job to do it correctly in the first place, b) you followed the schedule they had (supposedly) reviewed and c) if you are going to get blamed for anything that doesn't work out when you help out (surprise!) perhaps they shouldn't ask you to cover for them. Of course, what they want you to do is take the blame so they are blameless, and still have you help whenever they can get someone to free you up to do that.
