I believe it is essential for everyone to have uninterrupted time off. You're not much use to the business if you return back troubled and exhausted after your break because you never fully switched off because work kept calling you.
Whether you're on holiday or not, problems will crop up no matter how many you tried to put to bed before you left. Problems are no respecter of holidays; 'problems' never take a break. But, because the mobile phone has given us ubiquitous connectivity and blurred the lines between calls received that are personal or private, it's so much easier for work or clients to 'simply give you a quick call even though I know you're on holiday, and ask about...'; that would not of happened 30 years ago.
What annoys me is that knowing that because I can be called to fix a problem anytime, any place, anywhere (Martini Style!), this robs the caller of any inclination to fix what's usually a straightforward problem themselves. Plus - and by jimny this annoys me - is after the initial call (which has set your mind racing) you get no update saying 'problem fixed'; so you spend the rest of the day worrying about it, and if they cracked it. That makes for some holiday/day off!
Even in the darkest hour, love comes shining through.
Then it doesn't seem so far from me to you.
