I have one suggestion, in addition to the pact. You may want to offer your alters some time to do what is important to them, in exchange for never coming front while you're at work. Scheduling and planning, and coordinating among alters is CRUCIAL to functioning well with DID. If you can establish a routine with set rules that work for everyone, your system can stabilize much better and work together much better as a whole. As with any group of people, getting along as a system takes a lot of give and take.

Good luck to you!
