Communication process at your work?

How does your manager communicate new policies, open shifts, problems Etc?

I have two jobs and at my main job, where I'm going back full time shortly, we get all important memos via personal email. They have a company email but most people there don't use it unless they are in management. It was hard to get on it from home, I remember when they first issued them out, so I don't bother with that anymore because I get it all to my phone and can check it on my days off if I see fit. We have a shiftplanning type program where we can check for open shifts, sometimes they'll send out a general email if someone wants something covered, or the manager or other staff will text us if there is a more urgent need.

At my other job I consider that communication is inadequate. They have a company email that you can only check from work. I've asked to receive important updates and information via my personal email, which would be easy to add on to a group list. I don't work there weekly and so get out of touch with what's going on. I'll go back to work and there will be 50 emails, many of them irrelevant such as the cafeteria menu or why the flag is half staff. They got a staffing program that in some ways is nice, but it sends out a lot of unnecessary emails. The thing I really like about that staffing program is that I can check to see who I would be working with when I sign up for shifts. That way I can work with the people I love working with. I never get personal texts about open shifts, which is my favorite way of getting information. Most people nowadays carry a phone with them, it makes it easy to check emails and texts. Sometimes I will get phone calls, and they don't coordinate it there so I might get multiple calls from different people about an upcoming openshift.

Communication is so easy at my main job, which is why I decided to just go back there full time and only work the second job occasionally. I've given feedback and nothing has happened. They state that the reason we can't have access to the company email from home is that we are not salaried employees and they would have to pay us. I told them that I feel very disengaged, as a per diem employee, by not being kept up to date, sometimes to the point where I go to work and read an email from 3 weeks ago that I was supposed to get up-to-date on some education, and then I read a subsequent one telling me that I am out of compliance with the previous email, which is rather annoying.

So how are things done where you work? Are you happy with how things are done?
