I started a new job about a month ago. I'm in the IT department of a medium sized company. They have two offices that are relatively close together. When I accepted the job I understood that I would be working out of different locations on different days. I had assumed this meant something like one week at Location A and the next at Location B etc. Currently it's basically random and I often find out the day before. This is causing me stress and inconvenience. When switching between the two locations I need to bring my belongings and work gear (including a laptop and its docking station) so I need to bring a large enough bag on these days. Also I sometimes don't go straight home from work and go to other activities. I asked the manager "what is the rotation schedule?" and he gave a non-answer "there isn't one yet, it still needs to be created" and then walked away. I don't know why we even rotate between the two locations instead of just being assigned to one. It seems like everyone else is on a fairly fixed schedule.
In general I've been having a little trouble adjusting to the manager's communication style. I never get the chance to talk to him one on one. He always CCs the whole department when replying to emails. He seems sort of invested in getting out of doing work and just laughs at everything. He also seems to only be in the office for 4 hours at random times. I'm not saying these things are unethical or unprofessional, I'm just saying I'm not used to it.
What's the best way to address this issue? I think I should send an email to my manager asking for clarity. I'm having trouble knowing what exactly to ask for. For example:
"Hi Manager. I was wondering if I could get more details on my rotation schedule and where I can expect to be working? Would I be able to know a few days in advance instead of learning the day before where I'll be working from?"
