It's the weather, and everybody is getting spring fever. We had a meeting at work in early March. The boss man said " Just to let ya guys know, this happens every year right around this time. It starts getting a little nicer out, and everybody starts to get some type of spring fever. People start to get real prickly, and each shift bitches and moans about the other shift, and everybody starts to get irritated with each other. I have been doing this for 18 years, and it happens every year, right at this time. Try and relax and calm down, and realize that everybody is getting anxious and tired of being cooped inside all day. Do your best everyday, and try not to let others actions get on your nerves. Everything will calm down in the next month or so." - I have noticed this firsthand, and he was 100% spot on when the boss man mentioned this to everybody.
