excuse me for my not good English
I work as a freelance web developer for small to medium local companies and I work alone.
Sometimes it happens that I have too much works and projects going on at the same time, or maybe I gave my availability to a specific client for a week because they have a trade fair or something like that. So I must work hard and produce results as expected and planned.
Meanwhile, I receive new requests for meetings or new jobs from other established clients, I always answer the phone or by emails saying "I am sorry but I can't meet you this week because I have a mandatory project to finish which I have planned since months. I can meet you the next week by this date... etc".
Some clients seems not understanding at all what I say and they start to call two or three times a day, send requests by email and so on. Just to answer them on the phone or to send a reply by email takes me time and distract me, when I restart to work I need to refocus etc.
So, sometimes I literally turn off the telephone and close the email client so I don't get emails, calls or messages by any means. That can be for half day to one full day, then maybe I recontact them when I am less busy the day after or as soon as I can.
But while doing that I feel "guilty" in some way that I maybe can be rude or unpolite to clients.
How is your behaviour in these cases, are you available 100% of the time or you go "offline" when you are busy?
