Hi,
It is Company specific.
You have not mentioned whether you are hiring on permanent basis with six months probation period or for fixed contract period, say for 2 years, subject to renewal.
In general separation clause to talk about separation with notice ( 1,2 or 3 months as per Company requirement) or salary in lieu of that. Also partial notice along with pro-rated shortfall salary can be included in the clause. The general notice period is 1 month or salary in lieu of that.
In addition to the above you can add about termination of employment /contract in terms of breach of the terms of the employment, with one month pay.
Also include confidentiality/ non engagement of other employment (part time) during service/ jurisdiction in case of dispute clause
