I work on a pig farm power washing, according to HR when I signed on my hours were 5am to 1:30pm however my manager told me officially it’s just 8 hours from whenever I clock in, but since I’ve been here we haven’t worked past 12:30. Anyway Today I was power washing one room and my manager comes In and told me he’s going to another farm and to keep going until he comes back. I told him “hope there’s not a big issue and it doesn’t take a while” and chuckles slightly. He goes “why?” And I, once again, said “we just don’t wanna be here all day” and chuckled again. He then immediately gets an attitude and says “well you work when I say you work and your hours are when I say.” I then told him that HR told me I work 8 hours past clock in and that’s what’s on my hire sheet. He told me HR tells everyone that and he is the one who makes up my schedule and to never stand in front of him and tell him my hours again. He then knocked my headphones accidentally off the wall, breaking them. I told my dad about the situation and that I was getting ready to just walk out. My dad told me that I need to have thick skin working around different guys and that he’s only human. What do you think? Am I overreacting?
