Recently the IT manager/director has gone somewhat AWOL. This is a person who works remotely from home and simply works through VPN, email and phone. Ordinarily he has a routine of checking on the progress of work almost every hour, but usually 5-6x a day. In the last couple of weeks he has gone increasingly AWOL. His habitual checking on progress has turned into barely two emails a day and seeming very passive.
Yesterday I delivered a finished application to him on the network and he didn't even check it. I had to follow up with him two hours later to try and get at best a nonchalant response that lacked interest; and this was originally one of his dear pet projects. He hasn't made any mention of working on other things and recently expressed being tired of the company after 8 years. Other employees are also finding it hard to reach him for IT support as well. His almost non-existent communication combined with taking an extended number of early leaves or sudden sick days that's out of character for him has lead me to wonder if he's planning an exit. The problem is his lack of communication is stifling progress on IT projects and the CEO who I would usually go to is out of town. As a result, it has lead to an almost non-existent workflow. What I don't want is for him to suddenly jump back in to the flow and expect that we have been super productive and start wanting to know what we have been doing when there has not been any meetings or projects assigned. What is the best way to approach this situation?
