I work for a small company, and unexpected circumstances have left us with no contactable management, possibly for up to a week.
Currently, I work on two separate projects, A and B, under two project managers, Alice and Bob. Meanwhile, my line manager, who is responsible for allocating my time, has had to take leave unexpectedly. More senior management are also unavailable.
Both Alice and Bob want me to devote my time to their own projects, but neither of them has direct authority over me. To further complicate matters, Bob is based in my office, while Alice is based in our parent company in another country. In the circumstances, Bob is the most senior person in the building, but is no more senior than Alice.
I know that project A is more important and that my line manager would tell me to work on that one. However, I have no written confirmation of this and Bob is adamant that I should spend all my time on project B.
With no direct superior to contact, how do I allocate my time (with priority on project A) without appearing insubordinate to Bob?
Edit: I should clarify that Alice and Bob are completely unwilling to yield to one another, so the situation is an impasse with me stuck in the middle. Normally my line manager would handle this for me, but he's unavailable.
The most senior person in the building (Bob) wants me to do work that I know I shouldn't be doing. In practical terms, I have to do some work this week, so how do I proceed?
