New guy insists on helping when I don’t need it
I've been with the company going on 12 years and 3 in my current department. Part of my job involves carrying tires and car batteries. I took took the service writer position last October after performing the evening duties roughly 2 years. I know my capabilities and limitations.
This is where it gets tricky. Last week a "new guy" transferred from the front registers to my department to take over the evening shift (the two people who took it between October and then moved on for reasons). I've dealt with enough new people to understand there's a learning curb, but this guy thinks he knows more about my abilities and job than I do.
When I went to pull 4 tires for an order, he saw me carrying 2 at a time and started lecturing to "work smarter, not harder" took one of the tires from me and insisted on doing the same with the other 2. A job that normally takes 5 minutes to do took 10 because he refused to let me do it by myself, 20 if you consider it was 2 people doing it. The tires themselves weren't heavy to me (I've had 3 years to build up my strength and those tires were far from are biggest or heaviest). I told him I know my strength and can do it myself, but he didn't seem to listen.
Another instance I had bought tires to the counter to sell as carry outs. These tires were bigger, but not that heavy to me and I was only handling one at a time to put on the counter to get the DOTs off them. New guy sees and tells me I shouldn't be handling them because I'll hurt my back. I tell him I know my limits and to back off trying to tell me how to do my job.
I'm getting annoyed at this. I don't like complaining and I do get help when I actually need it (like getting a heavy battery off a shelf above my head), but this . . . I left my previous department mostly because of a coworker bullying me and pushing her work off on me (as in if she didn'twant to do something, she'd push it off on me or if I was doing work related to my job description she would belittle it to sound like I was doing nothing). This situation is demeaning. I know my limits, I know my department, I know my responsibilities. I've tried explaining that to him, but he either ignores it or isn't listening. My next move is to take to our supervisor about it, but if my words aren't getting thru to him our supervisor or manager's would have to.
Also, there's no chance of him stealing my job any time soon. New Guy has only been in the department a week and our manager already knows and has praised my work and quick learning. It's why he even considered letting me transferred in and why I was given first refusal when the Service writer position was opened. I say this because I have had new people (both male and female in both this and my old department) come in and tell me to my face they're going to take my job. While he hasn't said that's his goal, it still feels like the same level of disrespect when he tries to "help" me do things I can easily get done on my own and faster that doesn't involve his training.
If anyone has any advice before I take this to my supervisor, I'll be glad to hear it.
