I began working on one of the current biggest construction site of my country around a year ago. I'm the youngest, but paradoxically, I'm the only one with a diploma relates to construction work, and it was the first construction site of my co-workers (whereas I had others, I believe it's the reason I was hired). They have all been here for way longer than me.
I don't know how to stand up for myself when we disagree.
Sometimes it's about to work. We have to plan the entire site, and since it's a huge one, we have a lot of planning to do. We don't do them alone of course : workers give us their informations during meetings, and we change them on live. When I'm the one controlling the computer, my coworkers often stand up to walk to the projecting screen and guide me on how to change the planning, even when I don't need their help because I too can listen to the workers. It happened that I understood something, wrote it on the planning, and my coworkers asked me to change what I wrote. It also happened that, after they told me to change, the workers corrected “our” work and guide us through changes that, in fact, rearrange the planning as I understood it in the first place.
Sometimes, when we are not in meetings, my coworkers would tell me I need to be more strict with myself when I plan, because they don't agree with my vision. Last time, I split up one task into two, and he didn't agree, but when I tried to explain my reasoning he laughed and I completly froze, didn't dare to press my point further and so didn't give him my main argument and just made the changes he asked. I'll see what the workers think about the schedule in meetings.
Sometimes, it's not about work. We were talking about volcanos the other day, and I mentionned Yellowstone to be the most dangerous. They all, the four of them, contradicted me and told me it was Vesuve. I tried to press that it was Yellowstone, but they insisted it was Vesuve and I watched too much Hollywood, so I shut up. I looked it up later : Yellowstone seem to be more dangerous between the two. But I didn't dare to press. They also vividly criticize my pastries, that I bring into work at least once every two weeks. My main four coworkers alway belittle them, whereas my superiors vividly thank me, and chief laugh that his summer body will never be ready.
I want to be able to make my point be heard, but I don't want to have arguments in front of other workers in meetings.
I want to explain to them what I did and saw in my previous construction sites, but I freeze when they all laugh before I get to my point.
I want to stop bringing pastries, but I like to bake, and my chiefs are nice. It's a bit weird, but my chiefs aren't from the same company as us, therefore, they have no real power over our behaviors, just our work.
I want them to stop laughing at my hobbies, even though they can seem weird on the outside. At least I have hobbies, unlike them.
