New Job - Employer Won't Confirm If I Am W-2 Or 1099 - How To Confirm?

U​pdate! To answer a few questions-

I got paid today and they did take taxes out of my check!! So im sure its safe to say that I am W-2!

However, I agree with those that say I should find a new job. I do believe that his actions were retaliatory..seeing as though he apparently just fired someone for also asking him if's and why's. Before that person got fired, he suspended him for two weeks. Then I got the job. I also found out that before I got there they had 11 technicians. (high turn over) Three ​quit and two got fired. ​According to w​hat I've been told today, he is definitely the problem.

​Also, he was not here today so, I spoke with the person he ​told me to speak to and she said that​ I was right to ask, because he gave her a 1099 for tax season last year and she thought she was W-2. So it actually happened to her. Maybe that's why he ​was so mad?

Came back to say this - ​She also told me that when she first started she and the route manager (also a woman) were technicians when they started. The positions they have now were filled by two people that quit so he forced them to do it (her words not mine). After that ​I also had someone else (person training me) t​ell me that I need to be careful because the will put me in the office because I am a woman. I wholely believe this because the route manager expressed to me how she wishes he would find someone else to do her job because she too would love to be in the field. ????

​A​t this point most of it is all rumors because​ those people are ​not here to confirm this story. She's also the only one that was able to some way confirm he is capable of this type of thing. (1099 vs W-2) ????????‍♀️

I just started. I completed a W-4. I was advised that a W-4 is not confirmation if I am W-2. I asked my supervisor and he basically flipped out on me. Told me that 1099 is better "if you're running your​ own business." But I don't run a business so I can't help but think he meant "better for him". Then he said that all these things were really frustrating and that I need to speak to the manager under him. I spoke to her and she told me she doesn't do that stuff, he does.

That same day about 30 minutes after I got home my hours were cut for the rest of ​the week ????

Sooo...how do I get proof of W-2 employment. I know I can ask the IRS to send him a letter and ask for a W-2 for tax season. But how do I get confirmation​ for peace of mind?

Any advice is appreciated. Thank you!
