General Tier 1 - Posibiltiy of Working in EU countires

Hi, I am in UK with General Tier 1 VISA. I am getting lot of employment opportunites to join companies in UK but the job requires me to travel to other Europian counties. What I know is there is a restriction that I cannot be away from UK for more than 90 days. Does this apply for emplyment as well. Specialy if I join a UK company who has branches worldwide.
Need assistance thank.

i think if you are getting paid in the UK and paying taxes, NI etc in the UK then you will be fine as your employer would also be able to provide you a letter in this regard.
