Quoting Mrs. Post-tato Headô:" Middle of the night may not be best time to post this, but it's NOT okay for my boss to call and curse ... [snip!] ... what this post is about. I assume responsibility for that. But he could've called and said, "You need to get off your phone.""
I can totally relate to this. I worked in this bar for 2 years and my boss was the nicest lady ever...until she got drunk, which was like every night. She would constantly be on my case about something, sometimes it was worthy of me getting bitched at for but most of the time it was just because she was drunk and someone else pissed her off, so she would take it out on me. I can't count how many times she has made me cry. One time I was working a Tuesday night and the place was COMPLETELY empty. I had a huge headache and I put my head in my hands and rubbed it for like 10 seconds. Apparently she walked in at that exact moment and flipped the smurf out on me. She thought I was like sleeping or something and I tried to explain to her that I was just rubbing my head, but she wasn't hearing it. She even went as far as to call me a little bitch. I honestly don't know how I put up with it for that long.
Sorry I kind of went off there haha..but to answer your question, no he should not have talked to you like that. Yes, you shouldn't have been on your phone but there is a right way and wrong way to handle that situation. I'm sure all he would of had to do was say "Hey, I saw you were on your phone and we can't be having that while you're working." and you would have happily complied. I'm sorry he went off on you, that was very unprofessional of him.
