Can your employer controls what or where you go on ur rest days? I am being given a work phone, many times my employer or other stuff will try to contact me on a weekend regarding work. And i am a manager of a department therefore higher responsibility. However I felt that things gotten out of hand recently when I am being question on my personal time. 

- during the weekend which i am already off duty, I went for a short 2 days trip to the neighbouring country to destress and unwind myself from the stressful work. 
- my employer is looking for me on the weekend and I did not reply them till late at night as I felt that it's my rights to not reply any work related enquiries immediately when I am already off duty. I does that to set a boundaries to them that I will not always be on "standby" on the phone when I am off duty. 
- when I'm back to the office on Monday, I am being question about my whereabouts on my off days and why I did not reply or answer the phones. They said that its my duty to reply to the phone calls or text message even on weekends where I'm not working as I am a "manager". 
- I'm shock and i felt that my private like is being invaded.  Being a manager we have more responsibility. But I felt that we have our rights to our private time as well especially when we are off work. 

How can I reply to my employer? I felt that they have cross the line by invading into my private life and what I do off duty is non of their business and even if they provide me a company phone, this doesn't meant that I need to be on standby 24/7.
