One of our employee re-joined the company after 1.50 months - is there any rule for minimum time/break?

One of our employee re-joined the company after 1.50 months. His previous service was 4 years.
now whether his service will continue from previous or will be count as new.
is there any rule for minimum time/break required to rejoin in same company.

Hi,
Please clarify the period of break it is not clear. Are you meaning 1.5 months ? If it is one or two months and if it is already approved by employer, then you can treat the absence period as break-in-service and continue with old employment. If period of absence is more and if previous employment settlement is over then offer him a new employment.

period of break is 1.5 months only and his previous employment is settled.

Dear Friend,
There is no legal obligations of rejoining process and don't make this more critical, follow the simple way i.e show up as a new employee.

Hi,
If previous employment is settled then obviously you have no other option except to consider as fresh employment.
