OK, You guys haven't turned me in the wrong direction as far as mechanical things go so far. So here is my problem.
I have been at this new Dept. for a little over a month. There are three 24hr shifts (A, B, C) I got put on a shift That I was warned would suck. Reason I was giving was It has all the disgruntled workers. So far there is not an officer yet on my shift. just 4 firefighters. I lack the years of service to apply for the LT. position, but there are about 5 others that are.
So far I have picked up that 2 of the 3 guys I work with do not like me. One has 15 years of experience in other places, the other is just a guy like me. From What I have seen, and heard. They appear to be threatened by me. I guess cause I am only 24 and have 2 years in. They are older. One is 35 with 3 years in the other is 42 with 15 years. Both are STILL firefighters, hence why they are disgruntled. The older one has been fired from other places and almost got sent home today for disrespecting an officer and for disrespecting me in front of an officer. The younger one is a recovering alcoholic that wrecked his car once with a DWI and got of Scott free. of course he has allot to be mad at I have tried to get along and have always respected everyone I work with. But I have run out of ideas.
If we get the grant we wanted from the state i could move shifts to work with the guys I know and Get along with. But that's up in the air. Advice?
Edit: BTW the older one has made it clear that he does not like me. He orders me do do stupid stuff like wear my uniform shirt, under my class A shirt AND have on a tshirt underneath as well. Every other place In the world just wears white tshirts under class A's because it gets hot. I asked him why and he said cause if we get a fire we need to take off the class A's so they dont get dirty We dont have time to change clothes before a call. He does **** like that all the time.
